abstract = {Mass spectrometry (MS) is the method of choice for
high-throughput identification of immunopeptides, which are
generated by intracellular proteases, unlike proteomics
peptides that are typically derived from trypsin-digested
proteins. Therefore, the searching space for immunopeptides
is not limited by proteolytic specificity, requiring more
sophisticated software algorithms to handle the increased
complexity. Despite the widespread use of MS in
immunopeptidomics, there is a lack of systematic evaluation
of data processing software, making it challenging to
identify the optimal solution. In this study, we provide a
comprehensive benchmarking of the most widespread/used
data-dependent acquisition (DDA)-based software platforms
for immunopeptidomics: MaxQuant, FragPipe, PEAKS and
MHCquant. The evaluation was conducted using data obtained
from the JY cell line using the Thunder-DDA-PASEF method. We
assessed each software's ability to identify immunopeptides
and compared their identification confidence. Additionally,
we examined potential biases in the results and tested the
impact of database size on immunopeptide identification
efficiency. Our findings demonstrate that all software
platforms successfully identify the most prominent subset of
immunopeptides with $1\%$ false discovery rate (FDR)
control, achieving medium to high identification confidence
correlations. The largest number of immunopeptides were
identified using the commercial PEAKS software, which is
closely followed by FragPipe, making it a viable
non-commercial alternative. However, we observed that larger
database sizes negatively impacted the performance of some
software platforms more than others. These results provide
valuable insights into the strengths and limitations of
current MS data processing tools for immunopeptidomics,
supporting the immunopeptidomics/MS community in determining
the right choice of software.},
