Anyone have any experience with using Oregon State University Tidal Prediction Software on Linux?!

No, its unlikely you will get help with such a specific program on a general help forum like this.

If you can provide more background information, or make it a generic computing problem, then you will be more likely to get useful responses.

I was able to build an apparently working version of the program -- it seems simple enough in terms of programming design. Can't comment on the complexity of the tidal model though, not my thing.

Are you having problems running the program, or using it? If so, did you look through the supplied README file?

I have read the README and have previously made this work, think my main problem is things not being in the correct places. I am very new to Linux and really struggling with getting my head around it. How can I check whether files are in the right folder?

>How can I check whether files are in the right folder?
You will have to read the program documentation, study the code, ask the authors, use trial and error, or use a tracing program such as strace. There is no other way, as theoretically the program could look for the data just about anywhere. Practically, it will probably look in the folder your are executing in, ie "."

Looking *very* briefly at the code, I would guess your model.lst has to be in the same dir as you are running the program from, and the data might have to be in DATA

note that linux is case sensitive. "Data" is not the same as "DATA" or "data".
