# edfcat(1)

## NAME

	edfcat -- EDF file channel mixer/converter.

## SYNOPSIS

	edfcat *OPERATION* *OPERANDS*

## DESCRIPTION

**edfcat is a tool to manipulate EDF file channels.** Currently, two operations are supported: (1) ascii-\>edf conversion (multichannel conversion restricted to channels with identical samplerate), and (2) channel pruning.

- conv **FILE.ascii** **SAMPLERATE** **RECORD\_SIZE**

  Convert samples in **FILE.ascii** into **FILE.ascii.edf**. Multiple columns in the source file will be converted as individual channels.

  On success, physical\_min/max in each channel will be set to the absolute min/max of all channel data, widened symmetrically to whichever boundary is farther from 0 (thus, a range of -2:3 becomes -3:3, as will -3:2).

- prune **FILE.edf** **N1\[,N2,...\]**

  Create a copy of source file (FILE-mod.edf) only keeping channels **N1,N2,...** (1-based).
