realtime_receiver with dcm files

Hello AFNI world.

I am trying to implement a real-time neurofeedback system using AFNI and have been using the demo programs, which all work fine when I stick with .BRIK files. However, I’ve not been able to get to work when I try to feed it .dcm files. I do get afni to open and track motion correctly. The realtime_receiver responds with “connection established from host on port 50353 / ++ found close request for run 1, TRs = 0” and then nothing happens in the receiver demo window. I haven’t changed the localhost value.

I do get this warning when I start realtime_receiver: /usr/local/lib/python2.7/site-packages/matplotlib/ MatplotlibDeprecationWarning: The WX backend is deprecated. It’s untested and will be removed in Matplotlib 2.2. Use the WXAgg backend instead. See Matplotlib usage FAQ for more info on backends.

But that appears when I run it and it works with the .BRIK data.

Any help would be appreciated.
