Hi Freesurfer people,

I'm running the QDEC on schizophrenia and controls group. Some mystery error is occurring frequently. Due to this error, I'm not able to work properly. Below is the error message in italic.

Data table loading completed successfully. SUBJECTS_DIR is '/usr/local/freesurfer/subjects' *ERROR: QdecDataTable::GetFactor: '' is not in datatable!* *ERROR: QdecGlmDesign::Create: bad factor!*

I'm using linux gedit for creating qde.dat file. Is it because of gedit or something else creating the problem while copying from libre to gedit. How can I overcome this error? This is repeatedly happening and also testing my patience.

Would be great if someone helps me to get rid of this error ..!!
