# csv outputs

The Analyzer csv outputs for each pipeline contains some columns which are the same as in the raw data exported from EmotivPRO. This is detailed in the [EmotivPRO manual](https://emotiv.gitbook.io/emotivpro-v3/managing-your-eeg-data-recordings/exporting-an-eeg-data-recording/csv-files#eeg-quality). 

In addition to these, the Analyzer outputs will include different columns depending on the pipeline.
