The NOAA Fisheries Integrated Modeling System (FIMS) is a software system designed to support next-generation fisheries stock assessment, ecosystem, and socioeconomic modeling. A team of experts within NOAA Fisheries is designing and developing the system, and we are advised by the FIMS Council, which includes academic, industry, and international partners. Our software is currently operational for estimation purposes and we plan for it to be operational for management in late 2025.
Installing FIMS
A precompiled version of the latest release of FIMS is available from R universe by running the following code within R:
install.packages("FIMS", repos = c("https://noaa-fims.r-universe.dev", "https://cloud.r-project.org"))Users can also compile it themselves, like any other TMB package by running devtools::install_github("NOAA-FIMS/FIMS"). This workflow allows for the specification of a particular branch or tag using the ref argument.
Developers who are interested in building FIMS can clone this repository, e.g., git clone https://github.com/NOAA-FIMS/FIMS.git and build it with devtools::install(), which builds the package from the cloned files and installs the R library. Installing with devtools::load_all() is not recommended because it uses shim files for things like system.file(), which can cause FIMS to not function as expected. For example, if you try to optimize the same model twice, you will more than likely not get estimates of uncertainty from the second model run. Additionally, devtools::load_all() adds the debugger flag -O0 -g which leads to Windows users seeing Fatal error: can't write <xxx> bytes to section .text of FIMS.o: 'file too big. Thus, Windows users need to run withr::local_options(pkg.build_extra_flags = FALSE) at the beginning of every R session before calling devtools::load_all(). If you want to compile FIMS with the debugger turned on you will need to run the {withr} function in addition to manually modifying the call to PKG_CXXFLAGS in the Makevars.win file in src to PKG_CXXFLAGS = -DTMB_MODEL -DTMB_EIGEN_DISABLE_WARNINGS -O1 -g. For a list of development tools needed to build, test, and document FIMS see the on- and off-boarding repository for NOAA Fisheries Office of Science & Technology.
Getting Help
If you encounter a clear 🐛, please file an Issue with a minimal reproducible example on GitHub. If you are uncertain if you have actually encountered a 🐛, are looking for more information, or want to talk about some new ideas please use the Discussion Board to post your thoughts. Users, developers, lurkers, and anyone else interested in our project are welcome to join the discussions, this is a place for all members of the assessment and open-source software community to ask and answer questions, share updates, have open-ended conversations, and follow along on decisions affecting FIMS. Also, feel free to introduce yourself 👋 on the FIMS Discussion Board.
