## Running JETSCAPE/X-SCAPE with LHAPDF
89+
90+
[LHAPDF](https://www.lhapdf.org/) is now included in the JETSCAPE/X-SCAPE Docker image. Instructions to run JETSCAPE/X-SCAPE in Docker are [here](https://github.com/JETSCAPE/X-SCAPE/wiki/Doc.Installation.Docker.Linux). While inside the container, use [external_packages/get_lhapdf.sh](external_packages/get_lhapdf.sh) to download the desired set. For example, to download the JAM20-SIDIS_PDF_proton_nlo set, run:
91+
92+
```bash
93+
cd ${JETSCAPE_DIR}/external_packages
94+
./get_lhapdf.sh JAM20-SIDIS_PDF_proton_nlo
95+
```
96+
97+
The above script sets an environment variable `LHAPATH='/home/jetscape-user/.local/share/LHAPDF'`. Adjust as needed.
98+
99+
Add the set to PythiaGun in your user XML file:
100+
101+
```xml
102+
<LinesToRead>
103+
PDF:useHard = on
104+
PDF:pHardSet LHAPDF6:JAM20-SIDIS_PDF_proton_nlo
105+
</LinesToRead>
106+
```
107+
Or run the example [config/jetscape_user_nPDF_test.xml](config/jetscape_user_nPDF_test.xml) user XML file.
108+
109+
```bash
110+
cd ${JETSCAPE_DIR}/build
111+
./runJetscape ../config/jetscape_user_nPDF_test.xml
