[Homer-users] Changing laser name in Homer2

[Perdue, Katherine]

Hi Shannon,

It is probably good to double check the measurement lists in your old and new files and make sure that the only change between the two is the exchange of source C for source F. You can check this by looking at SD.MeasList in the old and new files, and making sure that the only difference is that in the first column, source C, represented by a 3, is replaced by source F, represented by 6.

If you just replace the SD file to be the same across all subjects, it will make the error go away, but it doesn’t change the fact that the channels may be in a different order in your two groups depending on how your measurement list was set up.

best,
Katherine

It worked, thank you very much!

Simply load the .nirs file as .mat file (load a.nirs -mat) and then change the SD struct in it to make them universal across all .nirs files. This same scenario also occured to me.

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!
