[Eeglablist] Numerical Values in STUDY Structure

[Julie Onton]

Good question.

Below is a script to help you find, load and plot your raw data.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% LOAD raw data:------------------------
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
basedir = '/home/you/whereyourdatais/';

subjs =
{'S01','S02','S03','S04','S05','S06','S07','S08','S09','S10','S11','S12','S13'};

subj = 3; % who do you want to plot?
cond = 1; % what condition number?

% for example, load ERSP:
load_string =
[basedir,subjs{subj},'\',STUDY.datasetinfo(1).filename(1:end-4),'.icaersp'];

% OR ITC
load_string =
[basedir,subjs{subj},'\',STUDY.datasetinfo(1).filename(1:end-4),'.icaitc'];

% OR spectra:
load_string =
[basedir,subjs{subj},'\',STUDY.datasetinfo(1).filename(1:end-4),'.icaspec'];

% OR topomaps:
load_string =
[basedir,subjs{subj},'\',STUDY.datasetinfo(1).filename(1:end-4),'.icatopo'];

% load the raw data into the variable 'RAWdata':
RAWdata = load('-mat',load_string);

% Mask an ERSP using calculated bootstrap limits (if you calculated them):

ic = 8; % choose IC to plot

oneic = ['RAWdata.comp',int2str(ic),'_ersp'];
oneic = eval(oneic);
% in case you want to see the removed baseline:
onebase = ['RAWdata.comp',int2str(ic),'_erspbase'];
onebase = eval(onebase);
% load the bootstrap significance limits:
oneboot = ['RAWdata.comp',int2str(ic),'_erspboot'];
oneboot = eval(oneboot);

maskERSP = oneic;
% zero out non-sig values:
maskERSP(find(oneic > repmat(oneboot(:,1),[1 size(oneic,2)])& oneic <
repmat(oneboot(:,2),[1 size(oneic,2)]))) = 0;

clim = 4; % set +/- color limits
figure; imagesc(RAWdata.times,RAWdata.freqs,maskERSP,[-clim clim]);
set(gca,'ydir','norm');
title(['Subj ',int2str(subj),'; IC ',int2str(ic),'; ',STUDY.condition{cond}]);
cbar;


Hope this helps,  Julie
