- June 16th 2008: The 'NOT' statement is now usable in the IDENTIFY section. This allows doing negative queries. For example:
DEFINE PR = 'C[20..100] H[30..200] N[1] O[8] P[1]' WITH DBR = (0,16), CHG = 1; DEFINE pcHead = 'C5 H15 O4 P1 N1' WITH CHG = 1; IDENTIFY phosphatedylcholine WHERE
PR IN MS1+ AND NOT pcHead IN MS2+ WITH TOLERANCE = 50ppm
to check if 'PR' ignored some PC lipids.
- June 16th 2008: A new function for the SUCHTHAT section: 'column(<regular Expression>)'. The given regular expression returns only the matching sample names. This is for a selective query.
