ultrasound-processing

This repository contains several processing scripts/documentation for ultrasound data

###Contents:

• extractaudio.py is used for batch processing audio extraction from ultrasound video.
• extractframes.py is used for batch-processing frame extraction from ultrasound video.
• conconcatenate.py concatenates .con files generated by Edgetrak
• ffmpeg_install_mac.sh installer script to automat getting and installing ffmpeg on Macs

---

The scripts extractframes.py and extractaudio.py assume that you have python and ffmpeg installed on your computer.

• Windows installation instructions
• To install on a Mac:
  • Download
  • extract from the zip file and re-name the folder ffmpeg
  • Place the ffmpeg directory somewhere your computer can find it. One option is moving the ffmpeg directory to /usr/local/bin which you can do by running sudo cp -r path/to/ffmpeg /usr/local/bin/ffmpeg in terminal.
• Alternative Mac installation (may be buggy): run the installer scrip included in this repository. Done by running the command sh ffmpeg_install_mac.sh in terminal from whatever directory you've got the script in. This will automatically download and move files around for you. It will ask for a password while running.

concontateate.py works with the output of Edgetrak. It assumes a particular file-naming convention for the .con files which is as follows:
SUBJECT_REPETITION_WORD_FRAME
where WORD may contain extra underscores
