Calling back to Matlab with pressed keyboard button - see what.txt
This code listens for keys that have been pressed and calls a Matlab callback telling the callback what keys have been pressed.

Transititioning from Matlab to Python

Transitioning to Python from Matlab

Indexing vs Calling

In Matlab, there is not distinction between indexing and calling. Both are accomplished with parentheses.

a = 1:5
b = a(2:3) %indexing

Simple script to plot worm movement. A move to using an animation module would probably be more appropriate.
import matplotlib.pyplot as plt
import h5py
import numpy as np
#SPEED_UP = 4
#DT = 0.05
file_path = u'F:/worm_data/segworm_data/features/798 JU258 on food R_2010_11_25__16_34_17___1___9_features.mat'
h = h5py.File(file_path, 'r')

Rough version of FTP calls for retrieving tracker data. Need to add on saving code and check possible change to change directory call.
try:
import cPickle as pickle
except:
import pickle
from ftplib import FTP
import re
import time #For modification time parsing
#For later
