Dan Marcus, Xiaodong, Wendy, Vincent, Curtis, Nicole, Tina

*VTK Bugs in 5.2 - These are issues with the integration of the meshing tools
**0007518 - vtkDataReader Memory Errors causes a seg fault
**0007511 - Bug in vtkSmoothPolyDataFilter causes a seg fault
**0007512 - vtkPlaneWidget Sphere Resizing - This is simply an annoyance

* [[Events:August2008XNATDesktop#Plan_for_supporting_initial_use_case|Plan for XNAT/Slicer interaction]]: 9: Sebastien, Katie, Wendy, Nicole, Jim, Vince, Steve, Curt, Dan
* XNAT Desktop, Web Services Use cases (Wendy review of last weeks meeting notes)
** Web services file repository api is currently on XND, but will also be supported on XNAT Enterprise (by January).
** Sebastien and Yumin are working on the current save dialog box and will think about how the remote repository should look for that.
** discussion of how extra data file names are handled in ITK (which files are actually written when you save a particular archetype).
*** idea:  save to temp dir to get file names.  Rather than changing all ITK io factory code to keep track of which files it wrote, the slicer code can keep track of what files are in the save directory before and after the Write method executes (this assumes that each factory will only save files in the single directory, but that seems like a valid assumption for all known code).
** discussion of refining upload uri also how to keep track of metadata to store with derived data
*** how much can be kept track of automatically in mrml?  Maybe a lot...

==2008-08-21==

Attendees: Xiaodong, Steve, Curt, Ron, Nicole, Marco, Katie

*[[2008-08-15-email-atlas-generation|Ron]]: Atlas generation for the EM segmenter. We need to develop an end-user capability to create atlases to drive the EM segmenter.
** what is the right approach?
** where is leverage with existing infrastructure?
** what needs to be done
** who will do it?
** Need to schedule a followup discussion with Brad, Kilian, Polina, Guido, Stephen, Jim, Ross (possibly at MICCAI)
* Report on NCI Slicer Course by Curt
** NIST BioChange 2008 challenge may be suitable for Kilian's change detection module
* NIH personnel told Ron that the wiki pages are not as up to date as they expected
** Everyone should be sure the wiki reflects the current state of their NA-MIC work
* Update from Marco on BatchMake coordination with GWE
** Plan is to wrap GWE for use with BatchMake and Julien is working on it
** Waiting for Kilian's updates for scripts
** Ron says we need users to be actively using tools so we have a clear story for renewal - Marco to look at the NA-MIC DBP projects and see which are good fits with GWE and Ron can help facilitate connection

* Nathan will discuss presentation of fluid mechanics projects.
* Update from Core 1 + Core 2 [[2008_Engineering_review_at_Utah | meetings in Utah]] earlier this week.
* [[Slicer3:Chain_CLMs | Discussion of Module Chaining]] (Marco and All)
** Requested by Core 1 to systematize common use case
** Need several steps in an analysis process to act like a single command
** Would like something akin to the EMSegment workflow wizard, but as command line module rather than built-in module

Highlights:

Nathan's overview: discussing visualization options for his fluid velocity vector fields for tractography algorithm. Steve mentions a few options: 
* A LDDMM module in Slicer2 that does animated vector field visualization (work done in collaboration with Johns Hopkins: Anthony Kolasny, Mike Miller, et al.). 
* Another option would be to try using ParaView as a way to flesh out specifics, and then build a more custom tool for tractography later. Will will point Nathan to documentation for file formats, data formats, etc. or help with any questions, and Nathan will try this out.

Discussion of these topics at the engineering review in Utah:

* chaining modules together
* grid wizard (Marco) for grid and batch computing
* Bspline registration
* setting up repositories for collecting slicer modules (as technology transition mechanism)
* how this will fit into the slicer build process
* diffusion weighted imaging, shape analysis, and segmentation
* dicom to nrrd converter...

Milestones were set for April-end, Project week, and AHM.

Module chaining discussion (see link above):

* Java version as first goal -- eventually C++ implementation. 
* Discussion about module discovery process and how will chained modules be packaged: (c++ stub programs? or 
or discovery find chain-descriptor xml files? shell scripts? (cross-platform issues)...)
* Goal: By project week in June we would like to be able to chain modules developed by Core 1.

Sebastien's update on module building: Wiki will be updated today with status. (link)

==2008-03-20==
Attendees: Tina, Jim, Will, Wendy, Xiaodong, Nathan, Martin, Marco
* [[2008_Annual_Scientific_Report|Progress Report]] - read over the assignments. We will look for progress from June 1, 2007 to May 30, 2008.
* June 23-27 is the summer project week.  We will make first pass on projects in late April.
* Module discussion: Martin wanted to understand the state of module creation and usage within Slicer. Sebastien is working on modules that are built against an installed module. Terry is working on built-in modules for Slicer. Jim is working on modules using CMake in the NTRIC repository.
* Nathan- write a command line, Slicer module that is a wrapper to a web service. Nathan thinks he can get this done prior to the June AHM. We referred to Jim's presentation at the Utah SLC Core 1/Core 2 meeting.
* We will talk about grid wizard next week at SLC


==2008-03-13==
Attendees: Jim, Nicole, Dan, Xiaodong, Vince, Sebastian, Alex, Curt, Steve, Will, Terry

* We are starting to use Categories to bin our pages.  [[SuggestedCategories]] - suggestions?

==2008-03-06==
Attendees: Steve, Jim, Katie, Nicole, Tina, Xiaodong, Marco, Ron

Highlights:
*Slicer page on wikipedia - http://en.wikipedia.org/wiki/3DSlicer.  All engineering core members should visit this page and edit as needed.  ASAP.
*dicom to nrrd converter in progress.  Xiaodong working on it and expecting to complete in a few weeks.
* [[2008_Engineering_review_at_Utah|March 24-26 Meeting in Utah]]

==2008-02-28==

* Attendees: Jim, Steve, Wendy, Katie, Tina, Jeff, and Marco (Grid Wizard Guy)
* Discussion on time series analysis (viewer, scene markup). Initial viewer will be a general tool for comparing images.
* Avalanche of new features in [http://gridwizard.org/gwe/index.html grid wizard and GSlicer3]
** Proxy around Command Line Modules
** Extends command line with specifications for ranges of values as well as specify remote resources (data) that need to be transferred to/from the grid.
** Uses Velocity for parameter template engine
** Grid selection and authentication still being refined for Slicer
** Could be extended to other grid types (LSF, etc.)
** Lots of information on the website.  Instructions for installation.  A bit daunting for non-grid people.  Some of us will have to work through the instructions step by step to evaluate.

==2008-02-21==

* Attendees: Xiaodong, Jim, Katie, Nicole, Will, Steve, Nathan, Tina, Ron, Padma, Marco

- Nathan brought us up to date on fluid mechanics tractography

- Padma Sundaram: SCIrun environment supports EEG processing

- Marco is releasing Grid Wizard alpha version

- Nathan brought up the helical digital phantom web service. Currently the thinking is that it can be accessed through a web service. We suggested that Nathan write a wrapper, consistent with Slicer's execution module, to invoke the web service. However, since it is not available in source form, NAMIC cannot accept it as part of the NAMIC Kit proper. We can guide Nathan in the execution of this module.

* Attendees: Ron, Will, Steve, Wendy, Nicole, David G, Mark S., Casey, Sebastien, Curt, Luca

* Look at [http://www.vtk.org/Wiki/VTK_Widget_Examples upcoming VTK 3D widgets]
* Review of projects from SLC AHM 2008 http://wiki.na-mic.org/Wiki/index.php/2008_Winter_Project_Week

===DBPs===

1 - Stochastic Tractography in Schizophrenia (need to be invited to follow-up TCon) 

2 - Cortical thickness analysis - testing EM segmenter to their data.  They estimated parameters and tested during the week.  The goal now is to compare ITK-MS and EM segment module to see how these two tools compare for cortical thickness.  They are reviewing the tools using the same patient data.  

3 - (Mark Scully) Legion segmentation using EM segmenter and other options - worked with Brad using 2 channels of data.  Flare as 3rd channel caused problems.  Desired to have T1/T2/Flair together as three channel dataset.  Marcel is going to deliver his segmentation algorithm software to them to compare results. 

4 - Robotic Prostate Interventions - (David Gobbi) Working on transrectal biopsy module for Slicer.  They had a previous module for transcranial biopsies.  One of the most exciting developments was a new prototol "open IGT-Link" which will replace navitrack inside Slicer.  Image transfer is working over this protocol.  A simulator is being developed for the robot.  A few VTK bugs may have been discovered during this process, but it isn't on the top priority list right now. 

5 - Prostate Cancer - Wrote new ITK filter that has been submitted to the Sandbox.  They are looking at spherical wavelets for shape segmentation.  The wiki page will be updated soon.

=== Other NA-MIC Projects ===


1 - Groupwise Registration - (Casey) New Bspline registration method is being developed here.  It has been used for another project by Casey (#6).   Page needs to be updated. 

2 -  (Need to be invited to follow-up TCon)

3 - (Need to be invited to follow-up TCon)) 

4 - (Need to be invited to follow-up TCon).  Page needs to be updated

5 - Incorporating DTI tools into NAMIC toolkit - They are gathering a dataset that has both structural and DTI data in agreement.  Previous dataset was missing part of cortex.  UNCDB2 dataset has full coverage of the brain.  Resolution is a bit lower, but full coverage is an advantage.  Page is close to up to data.  Just submitted a paper to ISBI 2008 and working on MICCAI paper, as well.  

* NITRIC is g-forge and would be a good place for automated build process for Slicer modules.  This could make it easier to configure Slicer in client labs without need to build from source. This is still being developed by the NA-MIC core team.  There is an entry on the collaboration section of the NA-MIC website.  Also www.slicer.org/Documentation link. 

6 - (Casey) Worked with Serdar using groupwise registration tool.  They are currently evaluating results of this study.  More images will be added.  

7 - (John Melanakos) Spent last week working with collaborators on the MICCAI paper.  Project page is well filled. 

8 - (Need to be invited to follow-up TCon)

9 - (Need to be invited to follow-up TCon)

10 - MRML scenes for execution model.  Some of the issues Brad was having have been resolved.  Alex is making adjustments to MRML library as needed for the EM segmentation model. 

11  - (Curt) Unstructured Grids in Slicer - Finite Element modeling process was originally in a standalone VTK application.  The first Slicer module integration did not use MRML based storage.  We are now creating subclasses of Model and Unstructured grid data for storage and display in Slicer.  Some minor issues need to be worked out, but the MRML extensions for UnstructuredGrid datatypes are working. 

12 - Python (Luca) MatPlotLib plots are close to happening within Slicer.  Steve believes it is 80% complete.  Python command line modules are working now. Multiple arguments had to be worked by Luca.  He has developed Python-based CLI modules.   The event broker is discussed here because it affects the interaction with Python, because a Mutex lock has to be placed on the MRML scene.   Dan has been helping with metamodules - a single Python module which calls other mothers  (hierarchical execution, recipes, etc.).  

* Ron asked about using this scripting technique for the ModelMaker.  Some of the parameter setting, etc. could be set in the top module.   Nicole will look at this.  Kilian said that he wanted to call the "modelmaker" from another module.  

* A need was identified for new wiki pages:  (1) scripted modules, (2) metamodules, (2) python scripted modules

13 - (Luca) Transform hardening - Sometimes images are not XYZ alligned.  How will command line modules treat an object if it is the child of a transform.  The module needs to be able to apply xforms to data (after hierarchy is flattened) to get xformed data.  Jim and Steve talked through this lately becomes of the transforms access two-directions (from parents / to parents, etc.)  They are looking at how to change the model. 

14 - (Steve) MRML support for out-of-core processing - Steve put a link to a new page.  Dan, Jim, Wendy, Steve, etc.  working through NAC renewal grant (5 years).  Multiresolution and asynchronous data are likely targets for this effort, but it will be a long-term effort.  

15 - Event Broker discussion - Steve has made process on this, but this wiki page is older.  See the event broker page.  (look at link under Objective).  New term "observation" :  completely introspectable.  A full dependency between objects is implemented.  When a subject issues a "modified" event,  Delete events are maintained.  Complete "relationship" management of the interaction between objects.  This helps by allowing asynchronous event processing.  MRML has been converted to use the event broker with asynchronous events managed by the Slicer GUI (async events invoked after GUI events are done).  This hasn't broken anything so far, but should improve scalability.   Dot logfile format can be generated for inter-object dependencies.  This can be used to help provide "who called who" traces.    Some special magic is done in MRML Display nodes.  They set "observation nodes"

==2008-01-10==
No tcon due to AHM

==2008-01-03==
* Attendees: Jim, Steve, Will, Brad Davis
* Topics:
** Jim and Will talked about leading the Monday and Friday sessions, and who would do what.
** We are going to send out reminders to the project leads to ensure that their project descriptions are up to date
** We discussed the software process project to make sure that we have a chance to address the Slicer build process, dashboards, etc.
** We decided not to hold the project wrap-up presentation at AHM; we will do that later at subsequent TCons. (We decided that we needed the time to actually work. We are concerned that we are starting to see too many break-outs and not enough time to work.)
** We keenly missed Tina and hope that she and her family are doing well.
