Dear DTK developers:

         I met a problem when using odf_recon from my shell script: "Error reading vector file DSI_vectors_181.dat".  Below is my command lines:

——————————————————————————–

jli@jli-ubuntu:~/collabs/tmp$ odf_recon "/home/jli/ifshome/collabs/tmp/ep2ddiffWIP96x96PAT.nii.gz" 31 181 "/home/jli/ifshome/collabs/tmp/dti" -b0 0 -mat "/tmp/dtk_tmp/matrices/temp_mat.dat" -p 3 -sn 1 -ot nii

Volume dimension: 192 192 55
Voxel size: 1.250 1.250 2.500
Reading recon matrix…done
Matrix file being used: /tmp/dtk_tmp/matrices/temp_mat.dat

Error reading vector file DSI_vectors_181.dat

My Diagnosis did not find any problem:

jli@jli-ubuntu:~/collabs/tmp$ echo $PATH
/home/jli/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/opt/dtk:/opt/dtk/matrices

jli@jli-ubuntu:~/collabs/tmp$ ls -l /opt/dtk/matrices/DSI_vectors_181.dat
-rwxr–r-x 1 root root 2172 2011-09-29 16:25 /opt/dtk/matrices/DSI_vectors_181.dat

Thank you,

You need to set "DSI_PATH" to the matrices directory.
