climax is a Command Line IMAge eXplorer

CLImax (a Command Line IMAge eXplorer)

Installing CLImax

We recommend that you install CLImax as a tool using uv:

$ uv tool install climax-rfglab

or

$ uvx --from climax-rfglab climax

A CLImax executable will be created in a bin directory in the PATH, which allows the tool to be run without uv. If the directory with the CLImax executable is not in the PATH, a warning will be displayed and the following command can be issued to add it to the PATH:

$ uv tool update-shell

CLImax can also be installed as a regular Python package using uv:

$ uv pip install climax-rfglab

or pip:

$ python3 -m pip install climax-rfglab

A note on the Python interpreter

CLImax requires that you have Python 3.10 or above installed.

Using CLImax

After installing CLImax with one of the methods above, You can invoke it with:

$ climax <filename>

You can also run CLImax without installing it, taking advantage of uvx:

$ uvx --from climax-rfglab climax <filename>

There are a few ways to open an image with CLImax:

• You can specifiy the path to the image that you want to open (e.g. tests/cells_movie.tif) :

    $ climax tests/cells_movie.tif
  

• Or you can indicate a folder (slices in this example) that contains an image sequence:

    $ climax ./slices
  

• If there are image channels split into different files, you can specify a group of substrings to distinguish which files in the folder belong to which channel. For example, to open the files in the slices folder containing the substrings '488' and '561' as two different channels:

    $ climax ./slices -s 488 561
  

• You can use a list of paths to concatenate sideways (i.e. display side-by-side, but all the images must have the same dimensions!!):

    $ climax cells_movie_1.tif cells_movie_2.tif
  

• You can specify the color map used to display the image. The color map defaults to 'gray'. Check here for a list of color maps.

    $ climax cells_movie.tif -c viridis
  

• Notice that if you try to open a color image, the channels will be split and displayed side-by-side (red, green, blue). Thus, for instance, if you open the CLImax logo:

CLImax provides a dashboard with additional functionality:

name	function
rotate	rotate 90° clockwise
flip h.	flip horizontally
flip v.	flip vertically
invert	invert color map
update	continuous/discrete update
x-y, z-y, z-x	slicing plane through stack
auto	automated contrast adjustment (min-mode, max-99th percentile)
