Output of jrc version

JRCLUST v4.0.0-beta-p1 "Edward"

The command you used

jrc preview D:\Dario\tmp\1097843a_g0_t0.exportedt.imec.ap.prm
jrc traces D:\Dario\tmp\1097843a_g0_t0.exportedt.imec.ap.prm

Hello,
I am using JRC4 to spikesort my data. I found a mismatch between the voltage traces plotted by the command preview and traces (look at sites 112 for an example). Shouldn't they be identical since I am using the same parameter file on the same data

?
Thank you
I have pasted below the output of the traces and preview command and the parameter file I am using.
