Updated run_writedataset.m to include streamed event markers + pnet.c 64-bit bugfix

[DMRoberts]

Two issues fixed:

1. The version of pnet.c included in the TCP/IP toolbox as a dependency to MATLAB was a bit out of date, and can crash 64-bit MATLAB (on Windows and OSX, at least). I've replaced it with a version updated by Mario Kleiner of Psychtoolbox to function on 32/64-bit MATLAB (and originally distributed with Psychtoolbox itself).

2. The function run_writedataset.m had not been updated for the newly enabled functionally of event markers within the real-time stream. I've updated it so that the event markers streamed through the system are now included in the produced EEGLAB .set file. This is useful for debugging hardware plug-ins, because the datafiles produced by the native EEG recording software can be more easily compared to the datafiles produced by the BCILAB stream. I also fixed a bug in run_writedataset.m due to what seems was a renamed stream field in onl_newstream not having been renamed in run_writedataset (timestamps_ptr to tmax).

Hi Dan,

thanks -- will merge!

Best,

PS: I think it would be a tad better to use onl_peek to get the most recent
chunk rather than doing it by hand (particularly now that the stream data
structure is more complicated). Ideally nothing except onl_* functions
should depend on any internal details of a stream buffer.

Commit Summary

• Changed 'timestamps_ptr' to 'tmax', as this stream field was renamed
  in a previous version of onl_newstream.m.
• Updated pnet.c to version compatible with 64-bit systems, as
  modified by Mario Kleiner and distributed in Psychtoolbox.
• Updated run_writedataset.m to include streamed event markers in the
  saved dataset.
