Permission denied - mac

[sundar07]

Hi
I have a naive problem. I would like to try out elastix for image registration and downloaded the mac version of elastix (5.1.0). I then added the path to elastix in mac terminal and tried "elastix -- help", but I get "Permission denied" error. It is likely to be a mac problem, which I am unable to solve. Any help will be great!

Below, I have copy pasted what I have tried in terminal.

(base) sundar@SundarsacStudio ~ % export PATH=/Users/sundar/elastix-5.1.0-mac/bin:$PATH
(base) sundar@SundarsacStudio ~ % export DYLD_LIBRARY_PATH=/Users/sundar/elastix-5.1.0-mac/lib:$DYLD_LIBRARY_PATH
(base) sundar@SundarsacStudio ~ % pwd
/Users/sundar
(base) sundar@SundarsacStudio ~ % cd elastix-5.1.0-mac
(base) sundar@SundarsacStudio elastix-5.1.0-mac % elastix --help
zsh: permission denied: elastix
