Ask for help :How can I read the weights file of SAM spatial filter?

[李卫娜]

Dear fieldtripers,
 
    I want to read the SAM spatial filters of my MEG data recorded by CTF151 MEG system in a motor task. It seems the file in a ".svl.max.wts" format describe the "weights" information, but I can't read the out. And I found that there was a "read_ctf_coef.m" file in "eeglab plugins" which is copyrighted to Robert, can returns the spatial filter cofficients for CTF MEG system, and these cofficients were not read from a file but already existed. Is this "cofficients" and my weights the same thing?
 
    The description of function "read_ctf_coef" is as follows:
 
function [coef] = read_ctf_coef
% READ_CTF_COEF returns the spatial filter coefficients for the CTF MEG system
% that has been installed at the F.C. Donders Centre (id 1706)
%
% This function actually does not read the coefficients from a file, but the 
% coefficients themselves are included in this function.
%
% The original location of the coefficients included in this file is
% odin:/opt/ctf/hardware/M016/M017_1706.coef
