		+	* Debugged my program which create the DWI phantom:
		+	** Tried to find parameters that fit well with the model we choose for creation of DWI
		+	** Obtained first results for DWI phantom with corpus callosum that I need to validate and then improve
		+
		+	* Discussed the algorithm we use for tractography comparisons with people I met at the meeting
