Install using a provided script.

python <user phenix>/modules/cryo_fit/steps/0_install_cryo_fit/install_cryo_fit.py
<cryo_fit.zip> <install_path>

Please use absolute path, for example,

python
/Users/doonam/bin/phenix-dev-2906/modules/cryo_fit/steps/0_install_cryo_fit/install_cryo_fit.py

  • user’s computer needs to be registered to his/her github account. Therefore, make github account (free), Generate a new SSH key and Add a new SSH key to your GitHub account
• If user's macOS shows, “xcode-select: note: no developer tools were found at '/Applications/Xcode.app', requesting install. Choose an option in the dialog to download the command line developer tools.”

• “-bash: libtbx.configure: command not found”
  • (in commandline)
  • export PATH="/Users/.../phenix-xxxx/build/bin":$PATH
  • source /Users/.../phenix-xxxx/phenix_env.sh
