All searches used carbamidomethylation on cysteine as a fixed modification and report
identifications at 1% spectrum-level and 1% proteoform-level FDR.
This benchmark compares the identification results of
TopFD and TopPIC in TopPIC Suite versions 1.8.1 and 1.9.0
with their default settings: at most one unexpected mass shift and no variable
modifications.
Version 1.9.0 identified 2.7% more PrSMs and 1.9% more proteoforms than version 1.8.1.
This benchmark compares four search settings of TopPIC 1.9.0 on the same data set,
database, and computer as benchmark 2: the default setting (at most one unexpected
mass shift and no variable modifications), a search with up to two unexpected mass
shifts (-s 2), a search with methionine oxidation as a variable
modification (-b var_mods.txt), and a search with both options.
All four searches used the same TopFD output, 16 threads, and 1% FDR at the
spectrum, proteoform, and protein levels.
Every setting is a superset of the default search: no PrSM identified by the default
setting is lost in settings b, c, or d, and no shared E-value gets worse. Setting b
adds 101 PrSMs and 58 proteoforms, mainly proteoforms with two unknown alterations that
the one-shift search cannot explain. Setting c adds 54 PrSMs and 41 proteoforms, and it
also re-explains 283 PrSMs that carried an unexpected mass shift in the default search as
proteoforms with one to three methionine oxidations and no unexpected shift, with much
better E-values. The two options are nearly independent, and setting d gives the largest
set: 3,027 PrSMs and 1,779 proteoforms, 5.4% and 5.5% more than the default setting.
Protein counts change by at most 5, so both options refine how proteins are explained
rather than which proteins are identified.
TopPIC matches theoretical fragment masses of a proteoform to the masses reported by
TopFD, which requires a valid isotopic envelope with several peaks. TopPIC 1.9 added post mass matching, which matches
theoretical fragment ions directly to centroided peaks after proteoform identification
to increase the number of matched fragment masses in identified PrSMs.
It is enabled by default and can be turned off with --disable-post-match
(-E). After the database search and E-value computation, each theoretical
fragment mass of a PrSM that no deconvoluted mass matched is searched in the centroided
MS/MS spectrum. A fragment is
accepted when its most abundant isotopic peak is present, at least
--post-min-peak-num isotopic peaks are present (default 1), and the observed
isotopic intensities fit the theoretical envelope. The step does not change the
identifications, E-values, or FDR; it only adds matched fragment masses.
The run without post mass matching is setting a of benchmark 3, which was run before
post mass matching was added to TopPIC and is equivalent to a run with
-E. Both runs use the default search settings of TopPIC 1.9.0 and identify
almost the same PrSMs. Post mass matching reads the centroided peaks from the SQLite file
that TopFD writes when it is run without -N.

Without post mass matching
With post mass matching
Each dot is one PrSM identified by both runs; its position gives the number
of matched fragment masses without (x) and with (y) post mass matching. Dots above the
diagonal line gained matched masses.
Post mass matching added a median of 12 matched fragment masses per PrSM (interquartile
range 8 to 15, maximum 40). The number of matched fragment ions
per PrSM rose from a median of 18 to 30. The added masses are mostly small (median 1.27 kDa)
and carry low charges (77% are singly or doubly charged).
