Hello,

I have run mri_annotation2label and then selected the labels corresponding to my ROI, creating a new annotation file using mris_label2annot.

When I load my new annotation file in freeview, the ROI's are displayed nicely in different colors. However the remainder of the brain is dark black and therefore difficult to see.

I have tried to change the default color of the remainder of the brain to grey by editing the aparc.annot.a2009s.ctab file for my subject so that my ROI keep the colors originally assigned to them, but all other regions are changed to:

127 127 127 0 (grey).

When I do this, my ROI's all become grey and the remainder of the brain stays as dark black.

Can you direct me as to which file(s) I need to edit to keep my ROI's in color but change the remainder of the brain to a different color (grey).

Thank you very much,

Laura
