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).
