Hi,
I am having troubles with PROBTRACKX with multiple masks as seeds. Simply put, I got
images with all zeros after running PROBTRACKX.
For example, with the sample DTI data in the FSL course materials, I tried using the
thalamus and the precentral gyrus as the seeds in Multiple masks mode without any
targets, I can't find a single non-zero voxel in the output of FDT.
I am quite confident with the data preprocessing steps because I did get sensible tracks, for
example, using pSTG as the seed mask, I am able to get the tracks projecting to the IFG.
But when I no tracks were found with pSTG and IFG as the seed masks.
Is there any sample data showing what an output would look like with multiple masks
mode?
Any input from you guys would be much appreciated.
Thanks,
Francis
