[FieldTrip] File Format Issue

[Rabbani, Qinwan]

Dear Fieldtrip Community,

I don't seem to have gotten a response back for my issue. Forgive me if this is too soon. Please direct me to the right resource if you know of one.  It's just a simple issue of formatting, but all the data is there.

I would like to add that the specific error I get is with the initial step reading in the spike data with ft_read_spike. The error simply says "unsupported file format."

I'm still new to all this and would really appreciate the help so I can move forward with the actual analysis.

Thank you all for your time,

Qinwan Rabbani

Dear Fieldtrip community,


I work in a medical lab doing DBS research. I am doing data analysis for my lab for use in a paper. I've never used Fieldtrip before so I've been following this tutorial: http://www.fieldtriptoolbox.org/tutorial/spikefield. I was able to successfully walk through it using the sample data. However, when trying to use my own data, I ran into a little bit of a problem. I tried to read in my data from the various different file formats available to me, but none of them seem to be supported.


The original spike/LFP data was acquired via an Alpha Omega system, which outputs the data into .mpax format. However, the data was then cleaned up to extract out only the relevant time windows using Spike2 (v8.06) software. The resulting data from Spike2 can be output into .smrx, .mat, .emf, .emw, or .txt format, none of which seem to be supported.


How would I convert my spike/LFP data from one of those formats so that it will be compatible with Fieldtrip? Ideally, I'd want to directly convert the already cleaned up data into a supported format such as .nex rather than having to use the not cleaned up data in the original ,mpax file.


I tried searching online but couldn't find anything that worked. I can't move forward with the data analysis until I figure this out. I'd really appreciate it if someone could help me out.


Thank you in advance,


Qinwan Rabbani
