Can't find 3dFourier

AFNI version info (afni -ver): AFNI version=AFNI_23.3.12 (Dec 7 2023)
Ubuntu version info: Linux, Ubuntu 18.04

Hello, I have a short question related to the 3dFourier.
I downloaded the AFNI following the instructions here: https://afni.nimh.nih.gov/pub/dist/doc/htmldoc/background_install/install_instructs/steps_linux_ubuntu18.html#install-extras-optional-but-recommended-for-bootcamp-prep

However, when I tried to run the code, I could find the message that '3dFourier: command not found'.
When I checked the folder, which includes the overall related files, I couldn't find the '3dFourier'.
Also, I download the '3dFourier.c' from the afni_src, etc., and put it into the folder, but it is not operating.
In addition to that, I tired to convert the '3dFourier.c' into exe. because I thought it was slightly different compared to other existing modules. However, it requires some other code files, and there are missing '.c' files that I can't find in the 'src' folder from GitHub (https://github.com/afni/afni/tree/master/src).

In this case, how can I get the proper 3dFourier file?

Thank you for reading.

Hi-

We retired that program from distribution in 2020, as it was no longer the most modern program in the distribution for doing its job: you should use 3dBandpass instead.

The list of retired programs is one section of the Classified Program list---that is, a list of pretty much all AFNI programs classified into categories to help users find things.

Also, 3dTproject might be very useful, if projection of signals is the goal.
