Hi Juan - You can see usage info for dt_recon if you run it without arguments:
USAGE: dt_recon

 Required Aruments:
   --i invol
   --b bvals bvecs
   --s subjectid
   --o outputdir
...

So --b takes both bvals and bvecs one after the other, and --s is the subject name as found under $SUBJECTS_DIR.

Best,
a.y

Hi, I am trying to make the recon with diffusion images for running tracula. I gave this command: 

set cmd = dt_recon

set cmd = ($cmd --b $SUBJECTS_DIR/esq-15-hc/0122816811_007_ep2d_diff_mddw_20_3mm_p2_20190405/processing/31190669_bvals

set cmd = ($cmd --b $SUBJECTS_DIR/esq-15 hc/0122816811_007_ep2d_diff_mddw_20_3mm_p2_20190405/processing/31190669_bvecs)

set cmd = ($cmd --i $SUBJECTS_DIR/esq-15-hc/0122816811_007_ep2d_diff_mddw_20_3mm_p2_20190405/processing/esq-15-hc_dwi.nii.gz)

set cmd = ($cmd --s $SUBJECTS_DIR/esq-15-hc/)

set cmd = ($cmd --o $SUBJECTS_DIR/esq-15-hc/0122816811_007_ep2d_diff_mddw_20_3mm_p2_20190405/processing)

echo $cmd 

$cmd

But ir marks two kinds of error: canīt fin bvals.dat or Eddy/Motion correct and stops.

Could yo help me?

Thanks,

JC.
