     * **peptides|q-value|min**: minimum q-value for peptide sequences calculated by Percolator.
     * **GENCODE|group**: relative location of peptides to GENCODE gene models. Values could be 'All_intron', 'All_intergene', 'All_UTR', 'All_exon_noncoding', 'All_transcript_coding', 'All_CDS', 'All_exon_coding', 'other', 'All_transcript_noncoding', 'All_transcript'.
     * **spectrums**: Spectrums matches with the peptides. The IDs look like "26N1_31599,1G48_65306", where "26N1" is the MS run ID in table S3 of the manuscript and "31599"
