It needs "Variables" not "Variable"

Hi FreeSurfer,

I am trying to run Glm for a group comparison analysis

I ran the mris_prepoc and mri_surf2surf and it completed without error. However, when I run mri_glmfit it gives me the following error:

gdfReadHeader: reading comp_groups.fsgd INFO: ignoring tag Variable ERROR: gdfReadV1: Input line 1, subjid = Cont_FreeSurf_BMAMDCONTROL20 Found 1 variables, expected. 0 FSGDF Format Error: file = comp_groups.fsgd, tag=Input

The "comp_groups.fsgd" file was constructed in line with the FreeSurfer rules...

For instance,

GroupDescriptorFile 1 Title Lista_Controles_y_Pacientes Class Home_Control Class Home_SC

Class Dona_Control Class Dona_SC Variable Age Input Cont_FreeSurf_BMAMDCONTROL20 Home_Control 27 Input Cont_FreeSurf_BMAMGCONTROL27 Dona_Control 38

Input Cont_FreeSurf_BMAMMCONTROL43 Home_SC 46 Input Cont_FreeSurf_BMAMMCONTROL5 Dona_SC 28 ...

Is there any problem with this format?

The data corresponding to each subject is locate inside the $SUBJECTS_DIR directory (i.e., $SUBJECTS_DIR/Cont_FreeSurf_BMAMDCONTROL20)

Regards,

Erick
