ipyrad

ipyrad is an interactive toolkit for assembly and analysis of restriction-site associated genomic data sets (e.g., RAD, ddRAD, GBS) for population genetic and phylogenetic studies. ipyrad Homepage

Getting Started¶

Following example uses rad_example which can be downloaded as per instructions on https://ipyrad.readthedocs.io/en/latest/tutorial_advanced_cli.html

curl -LkO https://eaton-lab.org/data/ipsimdata.tar.gz
tar -xvzf ipsimdata.tar.gz

Start by creating a new Assembly data1 , and then we’ll edit the params file to tell it how to find the input data files for this data set.

module purge
module load ipyrad/0.9.85-gimkl-2022a-Python-3.10.5
ipyrad -n data1

New file 'params-data1.txt' created in ........

params-data1.txt will be created on current working directory. Review and edit the paths in parameter file to match the destinations of input data, barcode paths,etc.
