Advanced options

usage: installscipion [-h] [-conda] [-venv] [-dry] [-noAsk] [-n N] [-scratchPath SCRATCHPATH] [-python PYTHON] path

     Installs scipion3 in a conda or virtualenv environment. Check all parameters bellow for a custom installation. If there are issues initializing conda you
     can set CONDA_ACTIVATION_CMD variable and it will be used instead of guessing. Typical values are . "/path/to/miniconda3/etc/profile.d/conda.sh" or eval
     "$(/path/to/miniconda3/bin/conda shell.bash hook)"

 positional arguments:
   path                  Location where you want scipion to be installed.

 options:
   -h, --help            show this help message and exit
   -conda                Force conda as environment manager, otherwise will use conda anyway if found in the path, else: virtualenv.
   -venv                 Force virtualenv as environment manager, otherwise will use conda if found in the path, otherwise: virtualenv.
   -dry                  Just shows the commands without running them.
   -noAsk                try to install scipion ignoring some control questions in that process. You must make sure to write the correct path where Scipion
                         will be installed
   -n N                  Name of the virtual environment. By default, if this parameter is not passed, the name will be scipion3
   -scratchPath SCRATCHPATH
                         Path to a folder working at high speed(like SSDs) to be used temporarily during processing.
   -python PYTHON        Python version to use in the environment. For virtualenv, default value will become "python3", otherwise argument will be
                         literally passed to virtualenv.Default value is 3.8 but up to 3.11 may work as well.
