h4. Reading config files (m files using eval)

When reading/writing files - such as config files - not everything will behave like in the matlab console. 

The way teh config files were being read was not working - was simply using eval. It was necessary to read the file manually, adapting the suggestion found here: http://stackoverflow.com/questions/185461/reading-input-m-file-in-a-main-m-file#185660

> (...)n a function we would create a text file, INP, containing our parameters. 

> We create this file in the directory returned by the ctfroot function. 

> Then, in MAIN, we would use the following to retrieve these parameters:

<pre>

  eval(char(textread(fullfile(ctfroot, INP), '%s', 'whitespace', '');

See commit:d9262cdbfb38d9262cdbfb38 on the jabuilder-int branch.

h4. Other input/output files

At the moment the input/output is done in the same folder where the the java class is being called from (hrir_final.mat, for instance).
