write_read_label_file(filename,label)
Writes label file. The returned structure has the following fields
filename output file
label a stucture containing the stc data with fields:
comment comment for the first line of the label file
vertices vertex indices (0 based, column 1)
pos locations in meters (columns 2 - 4 divided by 1000)
values values at the vertices (column 5)0001 function mne_write_label_file(filename,label) 0002 % 0003 % write_read_label_file(filename,label) 0004 % 0005 % Writes label file.
