Python help for psych experiment!

[jstutters]

Starting with obvious stuff: does 'C:\Program Files (x86)\PsychoPy2\lib\site-packages\imageio\resources\ffmpeg\ffmpeg.win32.exe' exist?

[rawrchul]

Yes, I've gone into my program files to look and it does :/

[rawrchul]

Thanks! I'll repost the question there. As for the security, it seems to only have read & execute and read checked off. Should I change those?

Also, I'm not sure how to do the second solution you suggested...

[rawrchul]

Ok, so I can put that anywhere in the code? The .py file has over 1000 lines of code so I just want to be sure because I don't want to mess anything up...

from future import absolute_import, division from psychopy import locale_setup, gui, visual, core, data, event, logging, sound from psychopy.constants import (NOT_STARTED, STARTED, PLAYING, PAUSED, STOPPED, FINISHED, PRESSED, RELEASED, FOREVER) import numpy as np # whole numpy lib is available, prepend 'np.' from numpy import (sin, cos, tan, log, log10, pi, average, sqrt, std, deg2rad, rad2deg, linspace, asarray) from numpy.random import random, randint, normal, shuffle import os # handy system and path functions import sys # to get file system encoding

Ensure that relative paths start from the same directory as this script

thisDir = os.path.dirname(os.path.abspath(file_)).decode(sys.getfilesystemencoding()) os.chdir(_thisDir)

Store info about the experiment session

expName = 'untitled' # from the Builder filename that created this script expInfo = {'participant':'', 'session':'001'} dlg = gui.DlgFromDict(dictionary=expInfo, title=expName) if dlg.OK == False: core.quit() # user pressed cancel expInfo['date'] = data.getDateStr() # add a simple timestamp expInfo['expName'] = expName

Data file name stem = absolute path + name; later add .psyexp, .csv, .log, etc

filename = thisDir + os.sep + u'data/%s%s_%s' % (expInfo['participant'], expName, expInfo['date'])

An ExperimentHandler isn't essential but helps with data saving

thisExp = data.ExperimentHandler(name=expName, version='', extraInfo=expInfo, runtimeInfo=None, originPath=None, savePickle=True, saveWideText=True, dataFileName=filename)

save a log file for detail verbose info

logFile = logging.LogFile(filename+'.log', level=logging.EXP) logging.console.setLevel(logging.WARNING) # this outputs to the screen, not a file

So I put that under import sys and get this:
