[Homer-users] Changing laser name in Homer2

[Shannon Michelle Burns]

Hi all,

I've been running an fNIRS experiment using The TechEn system and analyzing with Homer2, but after about half of my subjects one of the lasers used in my array (C) stopped working on the machine, so I had to switch the SD file to a different laser (F). It's in the exact same position, but is just another letter. Because of this though my data set currently cannot be analyzed together as half of them have a different laser in the probe geometry. Can anyone advise me how to edit the .nirs files in the second half of my data so that I can change laser F to laser C and make Homer think it's the same geometry again?

Thanks so much!
