I've currently installed rosetta3 on aws cloud vm under ubuntu OS (Ubuntu 20.04.2 LTS).
I try to use a protocol from Khersonsky et al. 2018 (PMID: 30270109).
In order to do so, a rosetta_scripts_jd3.default.linuxgccrelease file is needed.
However, I did not find such file under $ROSETTA/main/source/bin/
My rosetta version is: rosetta_src_2021.16.61629_bundle
I've compiled it with: ./scons.py -j8 mode=release bin
