[Mne_analysis] writing raw fif files

[Sebastian Pannasch]

Hi,

the beamformer algorithm says: 'ERROR in what_kind_of_fiffile: Cannot 
open data file'
I am using MNE-2.6.1

best,

     Sebastian

I myself have used the MNE code for reading and writing raw files, and I have not had any problems using them with SPM 5, SPM 8, and FieldTrip. What software are you having difficulty with?

It works, but the script somehow changes the structure of the raw data (which makes it impossible to use it afterwards with other software packages). Is it possible to get the raw data written in a new file exactly as the original data? This is not the case with the example script in its current form.
