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?
