[mathpluscode]

Subject of the documentation

What are you trying to do and which part of the code is hard to understand or incorrect
or missing? Please provide a link to the readthedocs page and code if available.

https://deepreg.readthedocs.io/en/latest/docs/cli.html#visualise

Click the link in See more details in its usage documentation. and it goes 404.

Oh the doc is here https://github.com/DeepRegNet/DeepReg/blob/main/docs/source/docs/visualisation_tool.md.

The relative place doesnt work the sameway as in markdown.

Also, change visualise to visualize ^^ in favor of us english.

Btw we need more detailed docs for this tool?
I have the png outputs and I literally just want to assemble them into one gif inside the folder :(

EDIT: I found the doc but it is a bit overwhelmed for me. A bit shame to admit but I finally used ffmpeg to generate the gif instead of our own CLI tool.

Besides this, I'm wondering what is the functionalities this CLI tool is offering against https://ffmpeg.org tool? @YipengHu
