So I added the new environment variable
AFNI_USE_ERROR_FILE
If you set this to
NO, then 3dDeconvolve.err will not be created. You can do this on the command line, via
3dDeconvolve -DAFNI_USE_ERROR_FILE=NO ...
or in the shell script somewhere before the program runs, or in your
~/.afnirc file.
This change is in the GitHub source repository now, and will be compiled into binaries overnight. You can update your installation tomorrow (via
@update.afni.binaries -d for example).
