some error using dtiMakeDt6FromFsl

[ping-doctor]

Hello everyone,

I preprocessed my data with FSL，and produced 9 output files( vg_00001_S0.nii.gz;vg_00001_FA.nii.gz; vg_00001_MD.nii.gz; vg_00001_L1...L3;vg_00001_V1...V3).so I used these files as input to created the 'dt6.mat' file using the dtiMakeDt6FromFsl function. and I am having some problems in getting this when I use dtiMakeDt6FromFsl, the following error occurs:

vg_00001_S0.nii.gz Data will be saved in G:\zc\00001...

Does anybody know what could be wrong? Thank you!

This is a bug (?) where vistasoft doesn't create a preferences file for itself on first run, and then crashes when it can't find said file. See my report further below, it also causes a different routine to crash as well. You can just create the preferences yourself by doing this:

addpref('VISTA', 'verbose',true);

Afterward it should run fine.

Hi All,

I will add a check for prefs in the offending function (mrvWaitbar), and if not found, then initialize them in order to avoid this error.
