A python command line tool to read an SCP-ECG (https://en.wikipedia.org/wiki/SCP-ECG) file and print structure information about ECG traces and metadata.
Currently following SCP sections can be read with this tool
- Section0
- Section1
- Section2 (partly)
- Section3
- Section5 (partly)
- Section6 (partly)
- Section7 (partly)
- Section8 (partly)
Section2 (Huffman encoding) is not interpreted currently, so if Section2 is available Section5 and Section6 samples would need recalculation using Huffman tables from Section2.
usage: scpinfo.py [-h] [--csv section_id] scpfile
positional arguments:
scpfile input SCP file
optional arguments:
-h, --help show this help message and exit
--csv section_id print leads in CSV format for section 5 or 6, specify here
a section id
There is a python based Docker image gitrust/scpinfo to run scpinfo.
Run examples
docker run --rm -it -v $(pwd):/home/docker gitrust/scpinfo example.scp
docker run --rm -it -v $(pwd):/home/docker gitrust/scpinfo --csv 5 example.scp
On Windows OS use %cd% instead of $(pwd) for volume binding.
