Thank you Eric for your reply,
can you please detail more,
as you in the attachment when I load the fif file in brainstorm then I have
2 file : link to raw file & neuromag channels
those what I want to reconvert to fif file
first of all at which type of file I should export it from brainstorm? and
then what code should In used in mne to convert it to fif file?

Hi! Thanks for the nice feedback!

The revamp of stc plots is still ongoing and some features are still
missing.
I investigated and it appears that the 'background' and 'foreground'
parameters
are not supported yet by the pyvista 3d backend.

A way to track the progress of this work is on:

https://github.com/mne-tools/mne-python/issues/7162

I will update this list and I believe this should be fixed shortly.

Dear mne programmers,

I load from a tutorial in brainstorm the fif file:
mind004_050924_median01_raw.fif
as you seen in the attached image after loading we have the channel and raw
file

The information from the file coil_def.dat is integrated in the channel
file when loading data from CTF .res4 or Elekta .fif files. But in my case
I I edited the coil_def.dat file and aslo I edited the channel file after
loading the fif file mind004_050924_median01_raw.fif,

My questions:

-Brainstorm does not provide any FIF writer. How can I write those file in
MNE Python?
-How can I deal with problem in mne ? editing the meg channel files and
coil_def.dat channel, and making the information from the file
coil_def.dat is integrated in the channel file then compute the forward
problem?

Best regards
A

Read, edit, save:

raw = mne.io.read_raw_fif(...) # filename, etc.
raw.info['chs'][idx][...] = ... # edit however you need
raw.save(...) # write to some new filename

Make your own coil_def.dat and use
https://mne.tools/stable/generated/mne.use_coil_def.html, see for example

as you in the attachment when I load the fif file in brainstorm then I
have 2 file : link to raw file & neuromag channels
those what I want to reconvert to fif file
first of all at which type of file I should export it from brainstorm? and
then what code should In used in mne to convert it to fif file?

I am not sure how to do what you want to do in Brainstorm, perhaps someone
else has an idea. If not, you might try asking the Brainstorm people. Once
you get the data into MNE via read_raw_fif, read_raw_ctf, or even
constructing a RawArray from MNE data, doing raw.save(...) will write a
FIF file disk (it is the only output file format we currently directly
support).

  I load the fif file in brainstorm and I have the 2 file as you see in the
attached image raw and channel, if I export them to matlab it seems to be
its extension name .edf and .pos respectively
the idea is to make them again as .fif file
I am interesting to load the fif file so that the info in the coil_def.dat
can be integrated after I made the changes in the channel file
BST team advice me to use the writing functions of the MNE-Matlab toolbox.
and to ask the MNE-Python community, they might have easier solutions

Thank you Eric for your reply,

You could try using the MNE-MATLAB functions (I think they come bundled
with Brainstorm?), feel free to read here to see if you can put something
together that will work:
