# Creating a custom report function

## Running a custom report within the reporting module

In addition to the [standard reports](https://ldevumd.gitbook.io/bittsy/data-output/standard-reports), the reporting module has an option for running a custom report. You will be able to write an additional report function that is used whenever you select this option on the user interface.

After the reporting module reaches its [first full release version](https://ldevumd.gitbook.io/bittsy/the-reporting-module#downloading-the-reporting-module), we intend to make it open-source. Instructions will be added to this page on how to add your own custom function or modify existing functions for your lab's general needs!

## Creating your own report from log files

Just like the reporting module's existing reports, you can pull necessary information to calculate and report measures of interest directly from [detailed log files](https://ldevumd.gitbook.io/bittsy/data-output/detailed-log-file) or via the [All Event Info](https://ldevumd.gitbook.io/bittsy/standard-reports#all-event-info) report type. You can use any programming language in which you have expertise (e.g. Python, MATLAB, Visual Basic in Excel) to parse, filter, locate/calculate values from log files. Feel free to make use of the community on our [Slack channel](https://app.slack.com/client/TB5CFBH6W/CB6979M2A) for any questions about working with log files or for inquiries about any similar custom scripts made by other researchers!

## Share your custom reporting function

Do you have a custom report function you have created to use with BITTSy logs? If you are willing to share it with other BITTSy users, we would love to make it available as a resource. You never know who will find it useful! Get in touch through our [contact form](https://docs.google.com/forms/d/e/1FAIpQLSc3U6Y2HNA4QIIzCWSPsRFK2ggBreS4jE82jt-U8E4zV6Xh3w/viewform) or on [Slack](https://join.slack.com/t/bittsysetup/shared_invite/zt-fgk0dqme-WqSDS51h1atlKI_uqUv9yA), and we will link your info here!
