AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

Hi
In real-time fMRI experiment, we want to send the output of SVM classifier to the stimulator as a feedback, but failed in making a connection between AFNI and stimulator through "TCP" and "serial". 
3dsvm: Connection to SVM host established!
++  3dsvm: Ready for real-time testing!
Can't connect? tcp_connect[connect]: Connection refused
PO: plugout ManOfLaMancha has broken connection!
     : iochan_goodcheck: no longer alive
CB: 3dsvm: Distance to hyper-plane =  1.731
CB: 3dsvm: WARNING: Sending data to SVM host failed!
Socket gone bad? tcp_alivecheck[tcp_recv]:Connection reset by peer
[hhe@cluster realtime.demos]$ realtime_receiver.py -show_data yes -serial_port /dev/ttys) -tcp_port 53214
waiting for connection...
established from host10.12.43.247 on port 52424
**HELLO string is not magic, want 0xabcdefab but have 0x3d302e32

In rt-test mode, how can I send the prediction for one TR data to the stimulator immediately?

Thanks, Yang Han
