Ok Bruce, mris_convert has worked, but I have no idea what the numbers in the asc-file might mean. Is there a chapter in one of the manuals which would tell me about it?
I did the mris_convert with the complete rh.occip.patch.flat which is not what I want but I assume it should work in the same way. Of course I get a long file, about 40% of the file contains float coordinates where the third coordinate is always 0.000000, e.g. 9.62000 -37.419998 0.000000 the rest of the file has three integer coordinates for each voxel (??) but the numbers have up to 6 digits, e.g. 146214 146207 144544 ?! If these are the voxel coordinates, which coordinate system is this?
