EDF Header Repair

This script fixes some possible errors in the header of an EDF/BDF file (European Data Format):

reserved fields: overwrite them with spaces
replace non-ASCII or control characters with ' ' (space) or a '.' (dot) in the local patient/recording fields
correct the separators of the startdate and starttime fields
in case the startdate or starttime isn't readable, reset it to 00:00:00 01-01-1985
correct the number of datarecords as advertized in the header and correct the file length
correct the header size as advertized in the header
correct digital/physical maximum/minimum fields in the header

Usage:


  edf-hdr-repair.sh my_file.edf

In case you want to repair multiple files (in the same directory), use the following command:


  for f in *.[eb]df ; do edf-hdr-repair.sh $f ; done

(Make sure the script is in a directory which is in your PATH variable e.g. /home/your_user_name/bin or use the full path to the script)

Remark: EDFbrowser has also a tool for repairing a broken header which is more powerful and can fix more problems.

System requirements: GNU/Linux & Bash & coreutils
