Hi rich, I suggested to Turck that he put his query into a different
string than the one about cys, because people might not be following it
anymore (I often stop following a string after a few messages, particularly
if its something I'm not to interested in). Maybe you should put your
answer into that string.

There seem to be very few people to which Finnigan will reveal the
secret Ion Trap Control Language; I've heard that this is because the
LCQ is easier to break via the misuse of ITCL compared to the misuse
of ICL on the TSQ's.
More annoying for me is how secretive Finnigan is regarding the LCQ
data file structures; I would like to be able to have my home-built
computer programs be able to directly read an LCQ file w/o having to
convert to a text or netCDF file. Its a mystery to me why its
necessary to hamper the efforts of users of ThermoQuest equipment in
their attempts to extend the utility and value of their product within
the context of their individual uses and interests. I think that
their reasoning is along the lines that this is necessary for some
sort of ISO9000 bull----.

Richard,
this is in response to the LCQ part of your message. It's good to hear
that other people doing the same thing that I am doing. The LCQ is
very sensitive in the nanospray mode. But, as you mentioned the
problem is finding the peptide ions. We also have to do many zoom
scans (10 per 100 Da) in order to find them. I wish there was a way of
automating this process of "zoom scan" walking. Has anybody developed
a method on the LCQ that does just that?
