[Mne_analysis] plot_label_from_stc

[Sheraz Khan, PhD]

please use following commands, they are data independent, requires only
anatomical information. mne.setup_source_space is the one you need for the
src file.


conductivity = (0.3,) #MEG only
model = mne.make_bem_model(subject=subject, ico=4,
                           conductivity=conductivity,
                           subjects_dir=subjects_dir)
bem = mne.make_bem_solution(model)
src = mne.setup_source_space(subject, spacing='ico5',
                             subjects_dir=subjects_dir,
                             add_dist=False, overwrite=True)

> With the command make_average_subject --subjects <list of subjects>
> Is there a way or command to create this bem directory and files?

>> Hello MNE experts,
>>
>> I have a question for creating a Label from a functional STC file
>>
>>
>>
>> I found the script plot_label_from_stc.py which is great!
>>
>>
>>
>> However when I use the function mne.stc_to_label I am running into a
>> problem
>>
>>
>>
>>
>> My STC file is an average and morph file and I read it via the command
>> mne_read_source_estimate.
>>
>> I don't have the source space and I am forced to save the label as
>> unconnected vertices.
>>
>>
>>
>> I try to reconnect the vertices in FreeSurfer but with no success so
>> far..
>>
>>
>>
>> Is there a way to overpass this problem in a way I can save my label
>> as a connected surface?
>>

>> Thanks in advance
