Hi,
frateMaps is a cell array. I would like to save images for each vector in frateMaps.
I could see the images for each loop but the images are not saved. I would like to save each image with labelling 1, 2, 3 etc based on loop number.
I tried to modify second parts of code but didn't work. could anyone please advise how to save? thank you.
for i = 1: length(fwdposx)
figure('color','w')
drawfield(frateMaps{i},'jet',max(max(frateMaps{i})));
titleStr = sprintf('%s%s%3.1f%s',tFileList{jj}(1:end-2),' Peak = ',max(max(frateMaps{i})),' Hz');
title(titleStr,'FontSize',20,'Interpreter','none');
axis off
axis image
drawnow;
ratemapImage= strcat(sessions{ii},[funcName,' Map Image ',date],'\',tFileList{jj}(1:end-2),'_forward rateMap_run');
imageStore(gcf,6,ratemapImage,150);%tif format, 150dpi
imageStore(gcf,3,ratemapImage,150);%eps format, 150dpi
close;
end

sorry .. images are still not saved. if I put loop by loop (e.g. frateMaps{1}, etc) each image is saved.
imageStore is own function as below. I didn't write the code and juz trying to modify what I want so I am a bit lost how to modify to save all images. thanks!
% Function for storing figures to file
% figHanle Figure handle (Ex: figure(1))
% format = 1 -> bmp (24 bit)
% format = 2 -> png
% format = 3 -> eps
% format = 4 -> jpg
% format = 5 -> ai (Adobe Illustrator)
% format = 6 -> tiff (24 bit)
% figFile Name (full path) for the file
% dpi DPI setting for the image file
function imageStore(figHandle,format,figFile,dpi)
% Make the background of the figure white
set(figHandle,'color',[1 1 1]);
dpi = sprintf('%s%u','-r',dpi);
switch format
case 1
% Store the image as bmp (24 bit)
figFile = strcat(figFile,'.bmp');
print(figHandle,dpi, '-dbmp',figFile);
case 2
% Store image as png
figFile = strcat(figFile,'.png');
print(figHandle,dpi,'-dpng',figFile);
case 3
% Store image as eps (Vector format)
figFile = strcat(figFile,'.eps');
print(figHandle,dpi,'-depsc',figFile);
case 4
% Store image as jpg
figFile = strcat(figFile,'.jpg');
print(figHandle,dpi, '-djpeg',figFile);
case 6
% Store image as tiff (24 bit)
figFile = strcat(figFile,'.tif');
print(figHandle,dpi, '-dtiff',figFile);
end
