Single pulse search tutorial
The goal of this page is to help the on-boarding of new students who are interesting in single pulse searches.
The tutorial uses PRESTO. Although PRESTO may not be the best for a computationally intensive pipelines, it is pedagogically useful by allowing the user to manually run each pipeline step.

Note, I providing the commands outside of singularity. Run them with singularity as you prefer.
What you need
- Data: short observation of a test pulsar
- Software: singularity image containing
PRESTO
Simple SP pipeline
Step 1: inspect data
Become familiar with the structure and contents of the data using waterfaller.py.
Example command:
waterfaller.py --show-ts --show-spec --colour-map='viridis' -d 57 -T 100 -t 5 --downsamp=8 --scaleindep DATA
Parameters to play around with:
- Turn on and off dedispersion
- Go to a different time in the file
- Change the downsample factor
- Look at data with and without independently scaling each frequency channel
