In addition to simply merging files, CSVDataMerge addresses a few added complications. IOWA GAMBLING TASK PSYCHOPY CODEThe program is free to use, edit, and redistribute for non-commercial purposes (GNU General Public License v3.0) and I provide open-source code with this manuscript. CSVDataMerge is a free-to-use Java program that automatically merges all datafiles placed within a “data” folder into a larger dataset file. IOWA GAMBLING TASK PSYCHOPY HOW TOIndeed, the user is only required to know how to install the Java Runtime Environment (JRE if they have not already), create and name a folder, copy-and-paste, and double-click. The objective of CSVDataMerge was therefore to provide a simple script that requires minimal setup and technical capabilities. Another useful R package, prepdat, does exist, which also allows users to compute things like condition means and perform data trimming (using R commands), which may be a useful alternative for many users. Other free-to-use programs exists that are not as easy to use and do not deal with formatting inconsistencies, unlike CSVDataMerge (to be explained shortly). There are also paid (previously free) programs that require the researcher to upload data to the web, which may not be acceptable for data security reasons. I note that some other external tools exist that require a bit more work to use, for instance, by creating a Visual Basic script for Excel. The researcher or student could also imagine writing an experiment-specific script (e.g., in R, MATLAB, or Python), but this could also be time consuming and may be beyond the programming capabilities of the individual. Simple copy-pasting of each individual dataset into a larger datafile is possible (e.g., in Excel), but this is both time consuming (e.g., if there are a large number of participants) and prone to error. For instance, when run online, PsychoPy can either store individual CSV files or create an organized database, but some forum discussions seem to indicate that the former option is more trustworthy than the latter. For some programs, it also depends on the options selected. While some programs have automatic, but proprietary, data merging programs (e.g., E-Merge for E-Prime experiments), others do not. Indeed, after completing data collection, most experimenters will want one large dataset with the data of all participants combined into one file (e.g., to import into R or another statistics program for data analysis). IOWA GAMBLING TASK PSYCHOPY SOFTWAREThe absence of a simple manner of concatenating together the individual datafiles in many such software programs represents a rather large inconvenience. These programs are growing in popularity, especially for online data collection (e.g., because they are free software and some popular paid software programs, like E-Prime, do not allow for online data collection), perhaps even more so recently with limitations on the ability to run experiments in the lab during the COVID-19 pandemic. Many such programs (e.g., PsychoPy and OpenSesame ) create individual datafiles for each participant, generally in CSV format. The program represents a simple solution to an inconvenience of certain experimental software programs (e.g., for designing and running psychology experiments). txt file extensions), but I will talk about the merging of experiment datafiles in the rest of this paper. In principle, the program could be used (without modification) for merging any type of CSV (comma-separated values) files with or without column headers (whether saved with. CSVDataMerge was primarily developed with the objective of merging together experimental datafiles (e.g., from individual participants in a psychology experiment). ![]()
