Hello all.
I started preprocessing my data and I got the following error using DTIFIT:
" Terminate called after throwing an instance of 'NEWMAT::IndexException'"
Then I checked with bedpostx_datacheck my fsl_analysis directory:
I got the following output:

num words in fsl_analysis/bvals
144
num lines in fsl_analysis/bvecs
3
num words in fsl_analysis/bvecs
432
number of elements in bvals is not equal to number of vols in data
number of vectors in bvecs is not equal to number of vols in data
Okay, then I checked the bvecs and bvals but they have the same number of elements.... Do I have to normalize them to unisize and if how? or is there another problem?
I would be very thankful for your help :)
Thanks and Cheers
Lys
