On the daq1 machine in the subdirectory /data/IAC you can create ntuples using the list file created that has 3 column (ADCid, Chan, Time) and the ROOT program
.L List2Ntup.C
List2Ntup("filename")
Create a text file called temp.dat delimited with tabs where the channel number is in the first column, the photon energy in the second, and the sigma from the gaussian fit is in the third column
Then do
.L LinFit.C MyLinFit(0,2)
E_gamma = 0.119322 +- 0.41761 + (0.937227 +- 0.000752989 keV/chan) *Chan#
Using the ROOT ntuple
MPA->Draw("0.119322+0.937227*evt.Chan>> SeRun_008(8000,0.5,8000.5)");
