Hi all,

I am doing longitudinal analysis (recon-all) and while running the long_mri_slopes using the following command, I am getting different errors for each run and its driving me crazy.

The command I am running :

long_mris_slopes --qdec ./qdec/long.qdec.Sub_7_t0t1.dat --meas thickness --hemi lh --do-avg --do-pc1 --do-spc --do-stack --do-label --time years --qcache fsaverage --sd /home/nk/freesurfer/subjects/

I could not make any sense as the errors as they are different every time and sometimes it gets completed aswel. The various errors are :

ERROR 1 : mri_convert splitting qcache stack did not work?

ERROR 1 : mris_label_calc intersect did not work?

ERROR 1 : mri_glmfit did not work?

These are for the same subject and for the same hemisphere. And once it completed for left hemisphere but threw similar error for right hemisphere.

Your suggestions would be very much appreciated.

PS This is not only for one subject but for most of them.

Thank you.

Regards,

Nabin
