Search space is a different species (congener surrogate)
CONGENER SURROGATE. No genome, transcriptome or reference proteome exists for Actinia fragacea, so the dataset was searched against the transcriptome-derived proteome of a different species in the same genus, Actinia tenebrosa. Every identification is therefore conditional on cross-species sequence conservation and protein counts are not comparable with same-species searches. The identified sequences belong to Actinia tenebrosa transcript contigs.

Original study vs CnidoSite re-processing

Parameter As reported by the original study As applied by CnidoSite
Search engine SEQUEST HT (Proteome Discoverer 2.4) Comet 2026.01 + Percolator (Crux 4.2)
Sequence database custom multi-cnidarian database /mnt/sdb/jackie/cnidaria_omics/transcriptome_proteins/Actinia_tenebrosa.rep.pep
Surrogate: transcriptome-derived proteome of the congener Actinia tenebrosa (22,231 representative proteins). No proteome of Actinia fragacea is available.
Enzyme (not restated) trypsin (fully enzymatic, 2 termini)  ·  up to 2 missed cleavages
Precursor tolerance not stated 10 ppm
Fragment tolerance not stated 0.02 Da
Fixed modification C+57.021464 (carbamidomethyl cysteine)
Variable modification M+15.9949 (methionine oxidation)
Decoy strategy Comet internal reversed (1:1)
False discovery rate 1% (Scaffold, >=1 unique peptide) q ≤ 0.01 at the PSM level (Percolator q-values, target-decoy); protein level q ≤ 0.01
Quantification spectral counting (PSMs)
Contaminants cRAP appended and flagged; 15 contaminant proteins identified and excluded from the reported protein list
Gene mapping Peptides are reported against transcript sequences. This species has no CnidoSite gene models, so no protein links to a gene page.
