| − | == User Accounts to Access NAMIC Data ==
| |
| − | | |
| − | FMRI and DTI datasets are currently available to NAMIC participants via the BIRN Controlled Infrastructure. In order to access this data, please use the following steps to create a BIRN account with NAMIC permissions:
| |
| − | | |
| − | * ** Go to https://portal.nbirn.net/BIRN/cgi-bin/public/arbirn.cgi and follow directions to set up a member account (NAMIC is a participant i.e. you don't need to sign up for guest accounts)
| |
| − | | |
| − | * ** Go to https://portal.nbirn.net/BIRN/cgi-bin/Projects/index.cgi?pid=NAMIC__0003 to request NAMIC related permissions on BIRN. See the [[DataRepository#Notes|Notes section]] for more information.
| |
| − | | |
| − | * ** Before you download data using the account you have created, please confirm with your PI that you have received adequate human subject training. If your site does not provide this training, please do this [https://www.citiprogram.org/registerselectinstitution.asp?strKeyID=9934456536544677479770 Human Subject Online Training] as an affiliate of Brigham and Women's Hospital and send a copy of your certificate to your PI for their records.

| − | * 6 Healthy Controls Data
| |
| − | ** All data were acquired on a 1.5T GE MRI Scanner using the Horizon LX software platform.
| |
| − | ** SPGR: [[Dartmouth_SPGR_Scan_Parameters|Scan Parameters and Data Structure]]

| |
| − | ** fMRI (ER-RECOG task):[[Dartmouth_fMRI_Scan_Parameters|Scan Parameters and Data Structure]]
| |
| − | *** NOTE: onsets for tasks included with data are WRONG. New onsets have been uploaded to [https://portal.nbirn.net/BIRN/cgi-bin/DataGrid/browse.cgi?browseloc=/home/Projects/NAMIC__0003/Files/Dartmouth/HealthyControls6 here]
| |
| − | ** DTI:[[Dartmouth_DTI_Scan_Parameters|Scan Parameters and Data Structure]]
| |
| − | *** The slices of the 3rd and the 6th datasets are in IS order, i.e., the first slice is the inferior most slice. The slices of the rest 4 datasets are in SI order.
| |
| − | *** Dartmouth DTI Protocol for Slicer can be found here: [[NAMIC-Dartmouth-2b12g-Volume_Protocol_File|Dartmouth Slicer Protocol]]
| |
| − | *** Converting the dicom images into nrrd format using [[NAMIC-Dartmouth-DWI-to-NRRD-Format|a simple MATLAB script]], and [[NAMIC-Dartmouth-nrrdheader|a sample nrrd header]]
| |
| − | *** Without any MATLAB or other pre-processing: [[NAMIC-Dartmouth-DWI|NRRD headers which use existing slice images from tar files]] and which can be loaded directly into Slicer
| |
| − | ** Hippocampus Traces: Hippocampal traces were made on an SPGR resampled to 1.015625 mm3 isotropic voxels and realigned along the long axis of the hippocampus. This reoriented SPGR volume is included with the traces. Traces were drawn using the ''Brains'' program.
| |
| − | ** Hippocampal ROIs: Binary Hippocampal ROIs have been uploaded in the same directory as the traces. These ROIs are in Analyze format. There are four ROIs for each subject (left hippo, left hippo smoothed 3mm FHMW, right hippo, right hippo smoothed 3mm FHMW). The smoothed ROIs have 'sROI' in the filename.
| |
| − | * MRI Data for 15 SZ
| |
| − | ** Data consists of DICOM slices for SPGR and trace files for various Frontal Lobe Subdivisions
| |
| − | *** SPGR: [[Dartmouth_SPGR_Scan_Parameters_Schiz|Scan Parameters and Data Structure]]
| |
| − | *** Frontal Traces: Traces were made on SPGR volume using the ''Brains'' program. Go [[Frontal_Structure_Listing|here]] for a listing of the structures available and the filenames associated with them.

| − | == Search for NAMIC Data ==
| |
| − | | |
| − | Users earch for data available on the BIRN data grid through metadata applied to the data itself. Each data object and collection can be assigned any number of metadata tags. Currently the metadata tags consist of items such as: Modality (DTI, T1, T2, etc.), Institution, etc.
| |
| − | | |
| − | To see an example of metadata on a data file, take a look at the following UCI file: https://portal.nbirn.net/BIRN/cgi-bin/DataGrid/meta.cgi?queryfile=/home/Projects/Study5000__0005/Files/Archive/UCI07110773.tgz
| |
| − | | |
| − | To search for data based on imaging modality, you can search through the BIRN Portal: https://portal.nbirn.net/BIRN/cgi-bin/NAMIC/index.cgi
| |

| − | == Replication of Data ==
| |
| − | | |
| − | Currently, the NAMIC data sets are stored in BIRN at:
| |
| − | | |
| − | /home/Projects/NAMIC__0003/Files (physicall located at NCMIR) <br /> /home/Projects/Study5000__0005/Files (physically located at UCI)
| |
| − | | |
| − | For redundancy in case a Birn Rack were to go offline we have replicated the data to the BWH rack in preparation for the Programmer's Week.
| |
| − | | |
| − | This can be seen when using 'Sls -a'
| |

| − | During regular use it is not important that the file resides in two places, but it should be understood that removing the file will result in removing both copies.

| − | As more data is added to NAMIC we can periodically run the following command to update the BWH resource (provided you have the correct permissions).

| − | <br /> Namic Domain Creation
| |
| − | | |
| − | '''Please note''' that users who previously belonged to the external domain have been added to the namic domain. If you use the SRB S-commands, this mandates a change to your .MdasEnv file if you wish for your default directory to be /home/<your_user_name>.namic or if your default directory was previously /home/<your_user_name>.external. Please update your .MdasEnv file to point to your new default directory.
