Hi Gayane,

what happens if you run the mris_calc command directly? Also check if all the inputs really exist. It could be that you need to update mris_calc there was a problem with long file names in an earlier version. Which FS version are you using?

Best, Martin

Dear list,

I'm running longitudinal two stage model as is described in the tutorial here: http://freesurfer.net/fswiki/LongitudinalTwoStageModel

First, I've proceeded with longitudinal pipeline all my data, second, I've created longitudinal qdec table, and then, I've started to qcache my data, which after few seconds ends up with error:

SUBJECT template_malfara fwhm 0 computing PC1

mris_calc -o /home/utente/Documenti/Gayane/POCD_quantitative/freesurfer_pocd/longitudinal_2013/template_malfara/surf/lh.long.thickness-pc1.fwhm0.mgh ./tmp-template_malfara_lh_thickness_Dkx9j1/beta1.mgh div ./tmp-template_malfara_lh_thickness_Dkx9j1/tp1.mgh

Saving result to '/home/utente/Documenti/Gayane/POCD_quantitative/freesurfer_pocd/longitudinal_2013/template_malfara/surf/lh.long.thickness-pc1.fwhm0.mgh' (type = MGH ) [ ok ] ERROR 1 : mris_calc compute percent change (pc1) problem?

Please, could you give me a hint how I can overcome this error?
