Snaphu is a script that unwraps complex Radar images. The compressed zip setup file can be downloaded from standford website. It should be installed using the zsh terminal and must be copied to system binareis(bin). I am on Mac OS Big Sur and I extract the snaphu zip on desktop next I open terminal and write this command. cd Desktop/snaphu/src and then sudo make instal The installation starts and returned with an error the man/man1 path doesn't exist So i manually created the path sudo mkdir usr/local/man man1

This time when I run the setup again no error shows but when I write which snaphu or whereis snaphu nothing shows.

Please guide me in installation of snaphu. enter image description here

  • As it's copied snaphu to /usr/local/bin, try invoking it with command /usr/local/bin/snaphu ?

    Do you have /usr/local/bin in your $PATH. If so, try rehash to instruct zsh to re-investigate the $PATH directories. Then try snaphu again.

macOS Big Sur now uses a root read only file system I see no mention of taking any steps to change this to allow the installation of this software.
