External Email - Use Caution Hello, I am trying to do a paired difference analysis of two runs of probtrackx (I have already put them on the surface). The two conditions are “central” and “far” for each subject. I have already checked the individual subjects data and it does indeed have values.
Here is a sample of my subject list: 100206.central 100206.far 100307.central 100307.far 100408.central 100408.far …etc. Here is my mris_preproc script: mris_preproc --target fsaverage --hemi lh --isp $in/FP/100206.central/lhsurf.mgh --isp $in/FP/100206.far/lhsurf.mgh --isp $in/FP/100307.central/lhsurf.mgh --isp $in/FP/100307.far/lhsurf.mgh --isp $in/FP/100408.central/lhsurf.mgh --isp $in/FP/100408.far/lhsurf.mgh … --out $out/preproc_FP_cf_lh/lh.paired-diff.FP_cf.mgh --f $sublist --paired-diff The output log shows no errors, the number of inputs equals the number in the subject list and it creates a file but it’s all zeros. I just have no idea as to why this would happen? Thanks, Sara Sims
