Flexible use of fullfile

Hi,

I have the following line in my script:

roi = spm_select('FPList', fullfile(roi_path), '^RA.*\.mat$');

Depending on the type of image I want to process, sometimes I need to replace RA with either S4RA, S6RA, S8RA etc. In the earlier part of my script, I have an input called Configuration (e.g., Configuration = 'RA'). I intend to use this input to change the type of image when necessary. Could anyone tell me how to work Configuration into the line of script above so that when I change the configuration to say, S4RA, the line above will change accordingly from RA to S4RA without my having to do it manually? I hope this is clear. Thank you!

roi = spm_select('FPList', fullfile(roi_path), ['^' Configuration '.*\.mat$']);

or

roi = spm_select('FPList', fullfile(roi_path), sprintf('^%s.*\\.mat$', Configuration));

Notice the change from \. to \\. when using sprintf.

This is great! I've just started using sprintf so this is a good lesson. Thank you so much, Walter.
