Great. We will review this soon. I'll work on getting the test file uploaded this week :)

The matlab reader?

Do you have a pdf or link to the spec of the format?

[MureziCapaul]

Hi @h-mayorquin ,

Yes, I basically translated to Matlab Code to python and added some optmimisations. I do not have any file specs.
I can try to inquire about the format spec, but since the format is likely closed (the Nicolet System is stil being sold by Natus) this might not be possible. I will keep you updated.

[h-mayorquin]

Thanks. Yes, if the spec is not available we work with the matlab then. I am of the opinion that partial reading capabilities (that might be wrong) is better than waiting for the perfect reader. I have not read your PR but we just need to add disclaimers in that direction. Thanks for the update.

@h-mayorquin Allright, that sound good. I will still get in contact with the company sales rep, he's apparently very helpful. The kind of validation I have is comparing the reader output with the Viewer-Software provided by the company. Signals, events, channels all match up for the handful of examples I looked at.

Hi.
This looks like a very big effort for porting this reader.
Thank you very much.
I also will try to read this "quite" soon.

If they can share a spec of the datalayout in bytes that would go great lengths to ease our job here.
