Hello, I was trying to create a cortical thickness map with constant values in order to perform some tests. At first I tried using mris_convert. I converted my thickness file into ascii:
mris_convert lh.thickness lh.thickess.asc then I used matlab to change all the values in the last column to 2,0. I tried to convert the ascii file back to surface file by doing mris_convert lh.thicness.asc lh.thickness but I got "Segmentation fault". How can I convert may ascii file into a surface one? After failling to acomplish this, I tried using the save_mgh and load_mgh file, nevertheless I'm not quite sure which input values are needed. Where can I put my fake values in the save_mgh file? And what is "vol"? Thanks, Ines
