Hi FSLers! I am struggling with the DTI Mode of FSL: 1. I can open FA data in FSLveiw 2D nicely, but I cannot open any FA-data (produced in FSL3 on Cygwin) in FSLview 3D. That means: It atually works but I just don't see anything! Is that normal? 2. I installed FSL 4 in a vmplayer. Atotest with the testdata worked fine. After Eddy corrent-correction (30 volumes of 30 have been processed. "Done!") it tells me ERROR: window name "prompt" already exists in parent window name "prompt" already exists in parent while executing "toplevel .prompt -borderwidth 5" (procedure "MxPause" line 4) invoked from within "MxPause " Done! " " (procedure "fdt:apply" line 313) invoked from within "fdt:apply .fdt keep" invoked from within ".fdt.apply invoke" ("uplevel" body line 1) invoked from within "uplevel #0 [list $w invoke]" (procedure "tk::ButtonUp" line 22) invoked from within "tk::ButtonUp .fdt.apply" (command bound to event) and: Errors: terminate called after throwing an instance on 'Newmat::InompatibleDimensionsException'. 3. Trying Bedpostx on another data I got THE SAME error message. What is wrong? How can I fix that? Thank you very much!
