In the case of Identification Complete mzTab files, the numbers of protein columns grow very fast because of the mandatory fields referencing ms run. #18
In the case of Identification Complete mzTab files, the numbers of protein
columns grow very fast because of the mandatory fields referencing ms run.
This situation is not very common but you can find it when converting a
mzIdentML file generated with a tool like pep2pro to mztab.
As a temporary solution the file can be generated as a Identification Summary
because in this case these fields are not mandatory.
Example:
20 ms_run
2 protein_search_engine_score
-mandatory columns in an Identification Complete mzTab
ms_run/protein_search_engine_score unrelated = 10 columns
-best_search_engine_score[1-n] = num protein_search_engines_score = 2 columns
-search_engine_score[1-n]_ms_run[1-n] = num protein_search_engines_score x num
ms_run = 40 columns
-num_psms_ms_run[1-n] = num ms_run = 20 columns
-num_peptides_distinct_ms_run[1-n] = num ms_run = 20 columns
-num_peptide_unique_ms_run[1-n] = num ms_run = 20 columns
Protein section total columns = 112 columns
