Greetings,

 I have has some problems implementing FSL, I want to do probabilistic fiber
tracking using Siemens 3T dicom volumes.
 From my dicom files (1+20 directions b=1000)  was able to create
Analyze 7.5, NIFTII, FSL NIFTII, and Analyze SPM files using
MRIconvert. But when I started using the 64 bit CentOS FSL 4.1.2 for
DTI eddy current correction GUI, I obtained the error message below
and the error was similar no matter which of the files I used:

____________________________________________________
wrong # args: should be "ecc_update_files w filename"
wrong # args: should be "ecc_update_files w filename"
   while executing
"ecc_update_files .fdt

   (procedure "tk::ButtonUp" line 22)
   invoked from within
"tk::ButtonUp .wdialog1.f4.but_ok"
   (command bound to event)

 I would appreciate information about what am I suppose to do next.
 Also, if  I just go ahead and do the BEDPOSTX estimation, I obtain the error:

 I am really confused about about the best way of advancing, and I
would appreciate your assistance.
 If I could some how call you, that would be extremely nice, but
email assistance would also be deeply appreciated.

Best regards,

Nicolás Lori.
