Dear Freesurfer experts,
I am trying to conduct the long_mris_slopes --qdec qdecfinal --meas thickness --hemi lh --do-avg --do-rate --do-pc1 --do-spc --do-stack ?do-label ?time time --qcache fsaverage command for my longitudinal processing. However I keep getting the error message:
mris_calc -o /directory/baseX/surf/lh.long.thickness-spc.fwhm0.mgh --label /directory/baseX/surf/lh.long.thickness-spc.fwhm0.mgh mul 100
mris_calc: Sorry, but I seem to have encountered an error. While accessing file 'mul',
I read online that this was due to a bug encountered in version 5.1, however I recently upgraded to version 5.3 and the error message persists. As my Long and base runs have been done in version 5.1 still, I was wondering whether in order to fix this problem the long and base runs need to be rerun with version 5.3, or whether the error I am encountering has another solution/ is caused by another problem entirely?
Thank you for your help,
Best Wishes,
Cathy
