Dear developers and advanced users,
I'm using Precompiled binary linux_openmp_64: Mar 7 2018 AFNI_18.0.25 in CentOS 6.9, bash shell and I get the following problem trying to use afni-suma talk using the following steps from page: [afni.nimh.nih.gov]
in detail:
# port for AFNI-SUMA communications, and end all other chatter on it
export cport = 12
@Quiet_Talkers -npb_val $cport

# set line thickness of SUMA surfaces sent to AFNI:
export AFNI_SUMA_LINESIZE 0.005

# Open talkable AFNI
afni -npb $cport -niml -yesplugouts &

# Choose ulay (anat) and olay (FA>0.2) in AFNI
plugout_drive \
-npb $cport \
-com 'SWITCH_UNDERLAY imit2w.nii' \
-com 'SWITCH_OVERLAY dt_FA.nii.gz' \
-com "SEE_OVERLAY +" \
-com "SET_PBAR_ALL +99 1.0 Plasma" \
-com 'SET_THRESHNEW 0.2' \
-v \
-quit

[gc@lugh gc_DIFFPREP11]$ PO: plugout 'plugout_drive' has broken connection!

apparently the AFNI output is fine but the connection is broken.
Any suggestion?
Cheers,
