Conversion (Homer3) .nirs to .snirf validation[BUG]:

[EwanMahe]

Hello everyone,

I have a question concerning the validation of the format of a .snirf file on Python. I convert a .nirs file to a .snirf file via Homer3 (v.1.80.2). When I use the validateSnirf() function from the snirf package, then result.display() to check the validity of this converted .snirf file, I get 120 WARNING and 2 or 3 FATAL (for aux1/dataTimeSeries and stim3/data for example) depending on the file selected. It told me that there is an invalid_dataset_shape. I don't understand because the file is supposed to be converted by Homer3, so I thought it would be valid, without errors. Does anyone know where this problem comes from, is it a problem with Homer3 (the file converted by Homer3 would not respect the specifications of the official .snirf format) or with the validateSnirf function of the Python package snirf ? This may also be a mistake on my part, as I am not an expert in this area. Sorry if the problem is obvious, or if it has already been solved previously.

Thanks in advance for your time and your help.
