Hello,
I'm trying to run the following script on a small sample of data but keep getting an error (Inappropriate coding in Test No.1). Can anyone help me see what I'm doing wrong?
Thanks,
Chuck

Hello,
Apologies if this has been asked before, but does anyone know if AFNI is compatible with the new mac M1 processor?

Hi,
1). Running @chauffeur_afni -input DSET results in an error --
\@chauffeur_afni -ulay sub-055_ses-01_T1w.nii
++ My command:
@chauffeur_afni -ulay sub-055_ses-01_T1w.nii
** ERROR: Xvfb -- not found in path -- program fails
++ DONE (bad exit): check for errors
2) Here's my output of afni_system_check.py -check_all :
afni_system_check.py -check_all

Hi,
Below is the error I'm getting:
** ERROR executing this command in the shell:
@chauffeur_afni -ulay "15_FieldMap.nii" -edge_enhance_ulay 0.5 -ulay_range_nz 0% 95% -pass -set_subbricks 0 0 0 -obliquify u2o -olay

Thanks, Paul.
So, I'm using the below code, but the program ends with an error. I think I'm making an error with the freq maps...but not sure. In the following, 16_FieldMap.nii is the phase file I get from the scanner and 15_FieldMap.nii is one of the magnitude files. Do I need to alter the phase file or is putting the -scale_freq doing this for me?

Hi AFNI Gurus,
I'm wrestling with a dataset that has Siemens GRE dual TEs field maps. Can anyone recommend an efficient way to use these in AFNI for distortion correct? There seems to be an easy approach in afni_proc.py for when one has two flip images (A-P, P-A), but not for dual TE maps. Any help would be much appreciated!!
Thanks!
Chuck
