Hi Esmael, Without knowing the details of your dead-time correction, I would say "maybe". I think we could almost certainly add the code to do the correction to the library. How dead-time corrections get added to the GUI might be a bit more work, but certainly possible. Doing dead-time correction for a data file from an unknown source/beamline/detector is sort of tricky. There are many ways to encode dead time (you might save ICR, OCR, LiveTime, DeadTime), and there is no universal standard. Some detection systems can have a two-stage correction. Even an easy-ish case might be: fluor_dtcorr = FeKa_MCA1*ICR1/OCR1 + FeKa_MCA2*ICR2/OCR2 + ... + FeKa_MCA32*ICR32/OCR32 which is actually sort of painful to do programmatically. This makes working with data needing dead-time correction challenging, as some knowledge is needed about how to do that correction -- this makes archiving data challenging too. I would like to advocate for beamlines to save a "dead-time correction factor" -- a simple multiplicative factor per detector channel, or even better to save "dead-time correction total fluorescence", especially for archiving data but even to make it useful in analysis programs. That is, I think it is ok for us to add some tools to help do dead-time corrections but it would actually be better for everyone to have such corrections done at or by the beamline. That's probably not your actual question but may be slightly related. ;). I would say we could certainly try to add any functionality for doing deadtime corrections.

Dear Matt, Dear All,

Is there a way to use our customized dead-time correction function in XAS viewer/Larch?

Bests,

Esmael
