Import excel file for Time-Frequency analysis

[Sebastian_Balay]

Hello. I´m a clinical neurophysiologist working in intraoperative neuromonitorization (IOM). I am trying to analyse motor evoked potential (MEP) through a time-frequency analysis. My IOM software only lets me export my data in excel files. I am trying to import it them to brainstorm but I can´t seem to manage to do it, I keep getting an error warning.

Thank you very much

You can open the files in Excel and save them as .csv (comma-separated values), then this .csv file can be imported in Brainstorm.

1. Right-click on a new Subject then Review raw file
2. Select your .csv file with the format Files of Type as EEG: ASCII text (*.*)
3. There are few parameters that you need to specify depending on the way the signals are saved in the Excel sheet
   
   
4. Finally, click on Import

Unfortunately, files in native Excel format (xls and .xlsx) are not directly supported.

Dear Raymundo, thank you very much. I’ve followed your advise, and did it successfully.
I have another question, does Brainstorm have a way to compare between the morlet-wavelet analysis results?
