-==== startup.m ==== 
- 
-When MATLAB starts, it will look for a **pathdef.m** file in its startup directory. 
- 
-Start up folder (in the MATLAB icon | Properties | Start in ) (e.g. D:\Sources\MATLAB) allows controlling different paths and other settings via startup.m file placed in the folder, e.g.:  
- 
-<code matlab> 
-disp('Welcome to physiology analysis...'); 
-set_sources_path; % set additional paths dynamically, e.g.  
-% addpath(genpath('D:\Sources\MATLAB')); 
- 
-cd('F:\Data'); 
-edit; 
-EditorMacro('Alt-Control-h', @createHeaderComment_dag);

 +==== Shifting colormaps ====
 +Sometimes the colormap plots are shifted after printing. To fix this:
 +- in Adobe Illustrator, click on the colormap, release clipping mask, and go to "Object", "Rasterize", in the "Resolution" part click on the "Use Document Raster Effects Resolution".
 +
 +You have to do it for each of the colormaps.
