## NAME

parseval - comparative analysis of two alternative sources of annotation

## SYNOPSIS

**parseval** \[*options*\] *reference.gff3 prediction.gff3*

## DESCRIPTION

Basic options:

- **-d**\|--debug:

  Print debugging messages

- **-h**\|--help:

  Print help message and exit

- **-l**\|--delta: INT

  Extend gene loci by this many nucleotides; default is 0

- **-V**\|--verbose:

  Print verbose warning messages

- **-v**\|--version:

  Print version number and exit

-

  Output options:

- **-a**\|--datashare: STRING

  Location from which to copy shared data for HTML output (if \`make install' has not yet been run)

- **-f**\|--outformat: STRING

  Indicate desired output format; possible options: 'csv', 'text', or 'html' (default='text'); in 'text' or 'csv' mode, will create a single file; in 'html' mode, will create a directory

- **-g**\|--nogff3:

  Do no print GFF3 output corresponding to each comparison

- **-o**\|--outfile: FILENAME

  File/directory to which output will be written; default is the terminal (STDOUT)

- **-p**\|--nopng:

  In HTML output mode, skip generation of PNG graphics for each gene locus

- **-s**\|--summary:

  Only print summary statistics, do not print individual comparisons

- **-w**\|--overwrite:

  Force overwrite of any existing output files

- **-x**\|--refrlabel: STRING

  Optional label for reference annotations

- **-y**\|--predlabel: STRING

  Optional label for prediction annotations

-

  Filtering options:

- **-k**\|--makefilter

  Create a default configuration file for filtering reported results and quit, performing no comparisons

- **-r**\|--filterfile: STRING

  Use the indicated configuration file to filter reported results;

- **-t**\|--maxtrans: INT

  Maximum transcripts allowed per locus; use 0 to disable limit; default is 32
