Trials.saveAsText(filename + ‘trials.csv’, delim=’,’,ĭataOut=) these shouldn’t be strictly necessary (should auto-save) Trials.saveAsExcel(filename + ‘.xlsx’, sheetName=‘trials’,ĭataOut=) I think this is the relevant part, but I’m not sure if anything is wrong with it. I went to coder view to see what the code looks like for saving data. Please submit your experiment using this link by Wednesday, 24 November at 5pm. 30 Please note that the instructions also explain how exactly the assignment needs to be submitted. What specifically went wrong when you tried that?: The instructions for the formative PsychoPy assignment are available from Tuesday, 16 November at 9am. I checked my data settings under experiment settings ( ), and they appear as in the screenshot below. ![]() I thought it might be an issue with the program instead, so I tried reinstalling PsychoPy standalone, and it didn’t work. files were no longer being saved, although I haven’t touched the code for that I’d only made that in builder view. I tried going back to the basic Stroop task ( Build your first PsychoPy experiment (Stroop task) - YouTube), something that’s saved data as csv. I’m trying to make PsychoPy save things in. you could have a set of practice trials in a loop, followed by a set of main trials, and these would each receive their own sheet in the data file.I noticed that my experiment was no longer saving data in. This way you can store multiple sessions for a single subject (use the subject as the filename and a date-stamp as the sheetname) or a single file for multiple subjects (give the experiment name as the filename and the participant as the sheetname).īuilder experiments use the participant name as the file name and then create a sheet in the Excel file for each loop of the experiment. If you’re creating experiments by writing scripts then you can specify the sheet name as well as file name for Excel file outputs. We have already provided two Excel files containing word lists for the. For example, with a standard data file in which response time has been collected as ‘rt’ there will be a heading rt_raw with several columns, one for each trial that occurred for the various trial types, and also an rt_mean heading with just a single column giving the mean reaction time for each condition. Output data is automatically generated after running an experiment (e.g. For some data, where there are multiple columns for a single entry in the header. Each column represents a different type of data as given in the header. Each row represents one condition (trial type) as given to the TrialHandler. xlsx files are widely supported, the older Excel file format (.xls) is not likely to be supported by PsychoPy unless a user contributes the code to the project.ĭata from PsychoPy are output as a table, with a header row. The file format is open and supported by nearly all spreadsheet applications (including older versions of Excel and also OpenOffice). For each of those entries the 2D array represents the condition number and repeat number (remember that these start at 0 in python, unlike Matlab(TM) which starts at 1)įor example, to open a psydat file and examine some of its contents with:Įxcel 2007 files (.xlsx) are a useful and flexible way to output data as a spreadsheet. if you added ‘rt’ data during your experiment using ~ then ‘rt’ will be a key). Each entry in the dictionary represents a type of data (e.g. The list of dictionaries provided to the Handler during its creationĪ dictionary of 2D numpy arrays. The extraInfo dictionary provided to the Handler during its creation Of particular interest might be the attributes of the Handler: extraInfo: They contain more information than the Excel or csv data files, and can even be used to (re)create those files. ![]() These files are ideal for batch analysis with a python script and plotting via matplotlib. The contents of the file can be explored with dir(), as any other python object. These files are designed to be used by experienced users with previous experience of python and, probably, matplotlib. This is actually a TrialHandler or StairHandler object that has been saved to disk with the python cPickle module.
