This application converts several OpenMS XML formats (featureXML, consensusXML, and idXML) to text files.

The goal of this tool is to create output in a table format that is easily readable in Excel or OpenOffice. Lines in the output correspond to rows in the table; the individual columns are delineated by a separator, e.g. tab (default, TSV format) or comma (CSV format).
Output files begin with comment lines, starting with the special character "#". The last such line(s) will be a header with column names, but this may be preceded by more general comments.
Because the OpenMS XML formats contain different kinds of data in a hierarchical structure, TextExporter produces somewhat unusual TSV/CSV files for many inputs: Different lines in the output may belong to different types of data, and the number of columns and the meanings of the individual fields depend on the type. In such cases, the first column always contains an indicator (in capital letters) for the data type of the current line. In addition, some lines have to be understood relative to a previous line, if there is a hierarchical relationship in the data. (See below for details and examples.)
Missing values are represented by "-1" or "nan" in numeric fields and by blanks in character/text fields.
Depending on the input and the parameters, the output contains the following columns:
featureXML input:
RUN
/ PROTEIN
/ UNASSIGNEDPEPTIDE
/ FEATURE
/ PEPTIDE
(indicator for the type of data in the current row)RUN
line contains information about a protein identification run; further columns: run_id

columns refer to the consensus feature itself, "..._Xi"
columns refer to a sub-feature from the map with ID "Xi" (no quality
column in this case); missing sub-features are indicated by "nan" valuesRUN
, PROTEIN
, UNASSIGNEDPEPTIDE
, PEPTIDE
linesWith the no_ids
flag, only MAP
and CONSENSUS
lines are written.
Output format produced for the consensus_centroids
parameter:
rt
, mz
, intensity
, charge
, width

Output format produced for the consensus_elements
parameter:

indicates the replication of the first element of the current consensus feature (for plotting)rt
, mz
, intensity
, charge
, width
, rt_cf
, mz_cf
, intensity_cf
, charge_cf
, width_cf
, quality_cf
"..._cf"
columns refer to the consensus feature, the other columns refer to the sub-featureWith the consensus:add_metavalues
flag, meta values for each consensus feature are written.
Output format produced for the consensus_features
parameter:
CONSENSUS
line above, followed by additional columns for identification datapeptide_N0
, n_diff_peptides_N0
, protein_N0
, n_diff_proteins_N0
, peptide_N1
, ..."..._Ni"
columns refer to the identification run with index "Ni", n_diff_
... stands for "number of different ..."; different peptides/proteins in one column are separated by "/"With the no_ids
flag, the additional columns are not included.
idXML input:
RUN
/ PROTEIN
/ PEPTIDE
(indicator for the type of data in the current row)RUN
, PROTEIN
, PEPTIDE
linesPEPTIDE
lines: predicted_rt

(predicted proteotypicity)With the id:proteins_only
flag, only RUN

With the id:peptides_only
flag, only PEPTIDE
lines (without the PEPTIDE
indicator) are written.
With the id:first_dim_rt
flag, the additional columns rt_first_dim
and predicted_rt_first_dim
are included for PEPTIDE
lines.
