Hi Deniz - It sounds like the reconstruction for this particular tract and subject may have failed. You can try reinitializing it by using the reinit variable in your configuration file (search reinit in the freesurfer email list archives for previous posts on this). If you try that and the error persists, I can look at the data if you upload the subject's tracula directories for me here: https://gate.nmr.mgh.harvard.edu/filedrop2/

Dear Tracula users, I reconstructed uncinate fasciculus using the latest version of Freesurfer and Tracula. However, there seems to be a problem with produced stats files in dpath folder . I have -nan values for the center_avg variables in the file "pathstats.overall.txt" and there is no entry at all for the file "pathstats.byvoxel.txt", it is basically empty. Do you know why this could be happened? Files look like this: pathstats.overall.txt Count 1500 Volume 35 Len_Min 35 Len_Max 35 Len_Avg 35 Len_Center 0 AD_Avg 0.000935047 AD_Avg_Weight 0.000935047 AD_Avg_Center -nan RD_Avg 0.000682719 RD_Avg_Weight 0.000682719 RD_Avg_Center -nan MD_Avg 0.000766828 MD_Avg_Weight 0.000766828 MD_Avg_Center -nan FA_Avg 0.224986 FA_Avg_Weight 0.224986 FA_Avg_Center -nan pathstats.byvoxel.txt # pathway start x y z AD RD MD FA AD_Avg RD_Avg MD_Avg FA_Avg # pathway end Thanks a lot for your help! -- D.
