Trouble with the compilier

[ChadSam]

I’m new user to Open Ephys. When I try to compile the OE data to plexon, the ephys2plx script fails at ephys2plx_mex.c

Error using mex

I have tried the script in two versions of matlab (2013a and 2015a) and get the same failure.

Any suggestions as to why the complier is failing. Im using windows 7. Data format is in Openephys format.

Hello everybody,

I am compiling ephys2plx_mex.c on Mac OSX 10.11.2 with Xcode 7.2 and it works, even though it produces the following Warnings:

MEX completed successfully.

Does anyone know what they refer to? Can they be fixed? As I reported in the Issue #146 : https://github.com/open-ephys/GUI/issues/146, I managed to convert OE data into .plx (Plexon) format only in single channel mode (SE*.spikes) and I did not manage to convert OE data in stereotrode (ST) or tetrode (TT) mode. Could it be related to the compiling?

Thanks in advance for the help, Diego.
