thank you for the answers! it is working fine now,
I have an additional issue though concerning the connectomes, the groupconnectome file seems to have changed path, I unzipped the lead data file as explained, but it still did not find any modality (indicating that no connectivity data is found)
I tried a dirty way of doing this by renaming groupconnectomes data.mat and placing them in a folder in dMRI and it seemed to work (at least it built the ea_pm) untill a certain point,
finally i wondered how in addition to the ea_pm we could get the meshes of the fibers to plot them in trackvis for instance?
Thank you again!
