PXD039172 · PRIDE record

Generated summary PXD039172 is a DDA label-free dataset (Mus musculus) with 98 runs, 98 samples and no enrichment step (whole proteome). It was reanalysed with MetaMorpheus 1.1.12. At 1% FDR the search reports 1,033,275 PSMs, 57,636 peptidoforms and 6,671 protein groups, and the repository holds 41,458 PTM sites for it. 6 open warnings about it are recorded.
Written from catalog fields only (D17), with no model involved. It says nothing the tables below do not.

Open findings

Recorded against this dataset: 0 errors, 6 warnings and 2 for information

calibration_failed warning
GPTMD/search ran on uncalibrated spectra (S7)
count_mismatch warning
The bundle holds 1.03328e+06 where the producer reported 1.03334e+06 (results.txt: All target PSMs with q-value <= 0.01 (pxreprise:DEF-PSM-1PCT v1)). Both numbers are kept; treat the producer's as canonical until the difference is explained.
low_core_use warning
15.14 avg cores of 32 allowed (S5)
no_sdrf warning
No SDRF was found for this dataset, so each run was given a synthetic sample of its own. There is no sample metadata: treat every sample as unannotated.
occupancy_not_stored warning
Of 276761 occupancy entries MetaMorpheus wrote, some are not in ptm_stoichiometry: 12 duplicate entry for one site and run (identical values; same protein group); 50409 site not in ptm_sites. 'site not in ptm_sites' means the entry's site has no ptm_sites row to key on; 'not determinable' means a cell's segments could not be assigned to its accessions from the sequences (QuantProject DEF-OCC-ACCESSION), which is never guessed. Absence of a row for these sites is therefore not NA. A 'duplicate' is a second entry for a (site, run) that already has a row: one with identical values loses nothing; one with DIFFERENT values means MetaMorpheus wrote two answers and the first in file order was stored (examples in bundle.json occupancy.differing_duplicates; which one should be stored is QuantProject's to define).
unplaced_ptm_sites warning
Some modifications on peptides shared between proteins were not written to ptm_sites for one or more of those proteins, because the peptide could not be located in that protein's sequence and the producer's residue spans cannot be paired with its accessions. Of the (PSM, protein) pairs affected: 2264 named a protein that does not contain the stored peptide -- typically a PSM ambiguous between peptide sequences (level 4 or 5), where this protein carries a different candidate than the first, which is the one stored. Sites on the other proteins of the same PSMs are written. Counts are in bundle.json under protein_databases.
collapsed_duplicate_rows info
The producer wrote some rows more than once, identical in every column, and the copies were dropped so each identifier appears once. Nothing was lost: the kept row is byte-for-byte what the duplicates said. Rows that share an identifier and disagree anywhere are still refused rather than collapsed. protein_groups: 3 identifier(s), 5 row(s) dropped, e.g. PXD039172:D3YY49;F6RR30;F8WIQ8 written 2 times; quant_values: 294 identifier(s), 490 row(s) dropped, e.g. PXD039172:P18_008_Parkin_B_KO1:label_free:protein_group:PXD039172:D3YY49;F6RR30;F8WIQ8:QuantProject:DEF-PROT-SPC written 2 times. The full list is in bundle.json under collapsed_duplicates.
occupancy_decoy_groups info
99 occupancy entries on decoy protein groups were not stored: MetaMorpheus computes them, and they are FDR machinery, not biology.

Every modification with a site on a target protein, most frequent first. A dash in the UNIMOD column means the modification has no UNIMOD term in the registry that searched it, not that it is unknown. One chemistry can appear under two names (UniProt's and MetaMorpheus's); the catalog's ptm_sites_by_chemistry view merges them.
