OK, the particular version of `dwi2fod` you’re using dates back from 11 Dec 2015 ([this commit](https://github.com/MRtrix3/mrtrix3/commit/72603c8e)) - the current version is `0.3.15-535-g21da6244`. Your version predates the changes that were made to bring the MSMT-CSD method into the `dwi2fod` command, which explains the error message.

As to why you’re using an old version despite a recent `git pull`, my guess is that your previous install used the old `PATH` setting, which used to be `{mrtrix3_folder}/bin`. This changed with version `0.3.14` so that executables are now located in `{mrtrix3_folder}/release/bin` (as detailed in [this post](https://community.mrtrix.org/t/major-update-to-mrtrix3/110) at the time). So if you haven’t updated your `PATH`, you’d still be using the executables left over from the previous installation, despite having just compiled the new ones… You should nowadays be able to use the `./set_path` command from the mrtrix3 folder to set that up correctly. I also recommend you remove the previous `export PATH=...` line from your `~/.bashrc` file to avoid further conflicts, and rely on the `./set_path` command to update it from now on. I also recommend you remove the `bin/` folder and all of its contents to make sure you genuinely are using only the most recent executables.

Incidentally, we are about to revert to the previous `PATH` location within the next few days, when we release a major update… I won’t go into the details of why these changes were made (it’s a long story), but hopefully reverting to `{mrtrix3_folder}/bin` will cause less confusion in the future - and we won’t be changing it again in a hurry…
