Spike2IO cannot read smrx recordings

[whbdupree]

I am unable to read recordings in the .smrx format

Yes. Only smr are supported.
I don't known how much smr and smrx are different. If it is only some conversion 32bit to 64bit this should be easy to adapt. But if smrx is a completely new file format then it is a piece of work.

Do you have small files you could give and specification of the format ?

I can't share any data from my current project for reasons; best not to use these at all to be safe. I will see if I can get a short snippet from an unrelated project.

If not too difficult, this snippet should be as small as possible and should contains all possible objects (signals, spikes, event, epoch..). Thanks.

Well I am totally unable to work with .smrx files at the moment. Do you have a sample of such a .smr file that you could upload or send to me? I could then have a colleague convert it to .smrx.

Does any of you have a specification of the smrx file format? I would like to add support for this, but I have not been able to find any documentation for smrx.

[samuelgarcia]

I still do not have theses specifications.
maybe a plexon custumers could ask for them diretcly ?
