# flat2aida(1)

Convert make-plots data files to AIDA XML format.

## NAME

flat2aida - Convert make-plots data files to AIDA XML format.

## SYNOPSIS

**flat2aida** \[*options*\] *flatfile* \[*flatfile2* ...\]

## DESCRIPTION

Convert make-plots data files to AIDA XML format. The output is by default written out to a file with the same name as the input (out.aida in the case of stdin) unless the **--output** option is specified. When specifying either input or output filenames, a '-' is used to refer to stdin or stdout as appropriate.

Histograms can also be filtered by histo path, using the **-m** or **-M** options for a positive or negative regex pattern patch respectively.

## OPTIONS

- **-h**, **--help**

  show this help message and exit

- **-o** OUTPUT, **--output**=*OUTPUT*

  Write all histos to a single output file. stdout can be explicitly specified by setting '-' as the output filename. This option will be disregarded if **--split** is specified.

- **-s**, **--split**

  Split histograms into individual files

- **--plotinfodir**=*PLOTINFODIR*

  directory which may contain plot header information

- **-m** PATHPATTERNS, **--match**=*PATHPATTERNS*

  Only write out histograms whose $path/$name string matches these regexes

- **-M** PATHUNPATTERNS, **--unmatch**=*PATHUNPATTERNS*

  Exclude histograms whose $path/$name string matches these regexes
