Input Details

Spectronaut Output File (input_file)

Spectronaut PTM output file containing differential analysis data

Index Column Name (index_col)

Column name containing position information in the format _X123_* where X is the residue and 123 is the position

  • Placeholder: PTM_collapse_key

Peptide Column Name (peptide_col)

Column name containing peptide sequences (format depends on processing mode)

  • Placeholder: PEP.StrippedSequence

UniProt ID Column Name (uniprot_id_col)

Column name containing UniProt accession IDs

  • Placeholder: UniprotID

Processing Mode (processing_mode)

Processing mode selection: Mode 1: Basic PTM processing with position extraction from index column Mode 2: PTM group processing with site probability calculations Mode 3: ProForma sequence processing with enhanced position validation

  • Options: 1, 2, 3

Modification Type (Modes 2 & 3) (modification_type)

Type of modification to process (e.g., Phospho (STY), Acetyl (K), Methyl (K)). Only used in modes 2 and 3.

  • Placeholder: Phospho (STY)

FASTA File (Optional) (fasta_file)

Protein sequence FASTA file. If not provided, sequences will be fetched from UniProt automatically.

UniProt Data Columns (uniprot_columns)

Comma-separated list of UniProt columns to retrieve when fetching sequences online

  • Placeholder: accession,id,sequence,protein_name

Output Filename (output_filename)

Name of the output file (will be created in the output folder)

  • Placeholder: curtainptm_input.txt

Sequence Window Size (sequence_window_size)

Size of the sequence window around modification sites (must be odd number). Default is 21 (10 residues before + modification + 10 after).

Outputs

Name File Type Format Description
converted_file *.txt data tsv Converted file in CurtainPTM upload format with PTM positions, sequence windows, and protein annotations
