Hi Liliana,
Thanks for your response. It is good news you can see them all and at least the files are fine. I checked my tracking.config, which is slightly different only for TPC21 and TPC22 (highlighted in red):
########################################################################
# TPC S21
########################################################################
processor Frs/TpcS21 FRS.StandardTpc
times[0:7] <- FrsTpcCrate.tdc0[16:23]
#for $i in [0:3]
# times[$i] <- FrsTpcCrate.tdc0[16]
#end
# second delay line has problems, we get better x-position if we take only data from first delay line
#times[4:5] <- FrsTpcCrate.tdc0[20:21]
#times[6:7] <- FrsTpcCrate.tdc0[20:21]
amplitudes[0:7] <- FrsTpcCrate.adc0[16:23]
fiber <- FrsTpcCrate.tdc1[23]
display xc in TPCs/TpcS21/xs
display yc in TPCs/TpcS21/ys
display x:y 1000,-50,50:300,0,200 in TPCs/TpcS21
display x 1000,-100,100 in TPCs/TpcS21
display y in TPCs/TpcS21
display x_fiber:y_fiber in TPCs/TpcS21
display checksums | gate_checksums in TPCs/TpcS21
end
########################################################################
# TPC S22
########################################################################
processor Frs/TpcS22 FRS.StandardTpc
times[0:7] <- FrsTpcCrate.tdc0[24:31]
amplitudes[0:7] <- FrsTpcCrate.adc0[24:31]
fiber <- FrsTpcCrate.tdc1[24]
display xc in TPCs/TpcS22/xs
display yc in TPCs/TpcS22/ys
display x:y 1000,-50,50:300,0,200 in TPCs/TpcS22
display y in TPCs/TpcS22
display x 1000,-100,100 in TPCs/TpcS22
display x_fiber:y_fiber in TPCs/TpcS22
display checksums | gate_checksums in TPCs/TpcS22
end

The only differences I can spot in TPC21 are commented out? However, I can try making that change to TPC22 and it should work. Yeah, I am starting from the histograms in the 'xs' and 'ys' folders in Frs/TPCs/TpcS##, and things are calibrating nicely as expected for the TPC41 and TPC42. I do have a photocopy of the log book for this experiment, but perhaps this information will be further back, when these calibrations were made.
Thanks,
Scott
