Hi,
So after about a week of loading and re-loading FSL, I think I finally have
it installed correctly...Only problem is I'm still having a problem with
FDT-bedpostx step.
When I run FEEDS, everything seems to pass including FDT. Doing "echo
$FSLDIR" yeilds "/usr/share/fsl", but when I try it out I get the following
issues: After running DTIFIT, everything seems to be okay except that at
the very end, I get the following error message in a separate window, while
in the terminal all it says is "Done"
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 317)
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)
Also, if I try running bedpostx_datacheck, I get the following info:

Now, I understood that you don't necessarily need to run DTIFIT in order to
go through the FDT procedure, but running the bedpostx_datacheck prior to
the DTIFIT stage yielded the exact same message. Any ideas? Could this
mean that the bvals and bvecs files are no good? Thanks in advance...
