To understand Dani's programs, there are two steps. First, you must learn Spanish.
Mostly the lab uses VisionEgg (also see mailing list and PsychoPy python libraries to help draw stuff.
Our psychopy and visionegg installation notes .
Python programming
Here is a file Media:Matlab-python-xref.pdf that gives equivalent code for doing array operations in MATLAB, Python, and R
rehash toolbox
in MATLAB is reload(modulename)
in python
clear all
in MATLAB is [vars().__delitem__(_k) for _k in vars().keys() if not _k.startswith('_')]
in python
If you are running from python prompt rather than IDE, execfile('myprogram.py')
executes codefile

never have your data file overwritten again! include the following lines in your python code:
from time import localtime,strftime
timeAndDateStr = strftime("%d_%b_%Y_%H:%M", localtime())
filename = 'aBindingExpData_' #include here whatever you want
filename = filename + timeAndDateStr #filename will now have date time and year tacked on the end,
outputFileStream = open(filename, 'a')
#### e.g. 'aBindingExpData_04_Aug_2008_22:46'
Data analysis
programming in R (data analysis) Python programming for data analysis
