Hi<br>
<br>
am trying to process some of the Philips DICOM we acquired, in order to
perform CSD. At the estimate_response stage it crashes, something went
wrong with 'axes specification' but nore sure what. Here is the
sequence of operation I go though:<br>
<br>
$ mrconvert -info DICOM/ ./mrtrix-data/dwi.mif<br>
[...]<br>
<br>
$ mrconvert dwi.mif -coord 3 0 - | threshold - - | median3D - - |
median3D - mask.mif<br>
[...]<br>
<br>
$ dwi2tensor dwi.mif dti.mif<br>
[...]<br>
<br>
$ tensor2FA dti.mif - | mrmult - mask.mif fa.mif<br>
$ erode mask.mif - | erode - - | mrmult fa.mif - - | threshold -
-abs 0.6 sf.mif <br>
$ estimate_response dwi.mif sf.mif response.txt<br>
<br>
estimate_response: incorrect number of axes in axes specification
"-0,-1,+2,+3"<br>
*** glibc detected *** estimate_response: free(): invalid next
size (fast): 0x000000000194c420 ***<br>
======= Backtrace: =========<br>
/lib/libc.so.6(+0x775b6)[0x7f4f4d5065b6]<br>
/lib/libc.so.6(cfree+0x73)[0x7f4f4d50ce53]<br>
etc...<br>
<br>
Am trying to diagnose if I'm doing some basic error, or if there's a
problem with the way the axes are read from the DICOMS?<br>
Any suggestion?<br>
<br>
Ph<br>
