Here's my simple, crude python code to convert MSF to SQT format, and
I confirm that it can be converted to pepxml with TPP Sqt2XML script.

Few things to mention:

* Sqt2XML script truncate terminal AA at both ends, but MSF does not
have that info. So I put a dummy AA 'X' at both end.
* I still cannot find the AA modification info in MSF, so calculated
mass in ''Match' record can be incorrect depending on modification.
* deltaCn has various definitions (I didn't know that).

 I took the original definition for this script.

You can run this with the following simple command (after changing
filename & permission, of course):

./msf-to-sqt.py my_file.msf

I think there is an expert for this kind of task (inside TPP project).
I post this to save his/her time to dig MSF schema (that's what I did
yesterday). Of course I am happy to see him/her to take my code, and
make a single script to convert MSF to pepxml directly. :-)

Cheers,

Taejoon
