PRM Command Line Tool

The cnf command line tool allows users to prepare their calvin-network-data for running the HEC-PRM model or export as delimited matrix file.

The HEC-PRM code is distributed as a windows binary. Further, HEC-PRM uses DSS formatted files as input. We use the DSSVUE software to transfer data into and out of the DSS format. While, DSSVue is written in JAVA, precompiled libraries for this package only work in the Windows environment. For these two reasons, if you are running this software on MacOS or Linux, you will need to run a Windows emulator, like wine.

Requirements

• NodeJS: use apt-get (linux) or install from website
• git

Quick Start

# pull down data (you may have already done this)
git clone https://github.com/ucd-cws/calvin-network-data

# install cnf cli via npm
npm install -g calvin-network-tools

# install and download of HEC-ROM library, 
# Sets up .prmconf file in home directory. follow prompts.
# will be asked for full path to data repo pulled above
cnf library init

Matrix

Create a delimited matrix file to run 3rd party solver.

Example:

Entire network

cnf matrix --format=csv --ts=. --to=network --max-ub=1000000000

Sub-network with limited time range

cnf matrix --verbose --format=csv --start=2002-10 --stop=2003-01 --ts=. --fs=, --to=network --outnodes=nodes --max-ub=1000000000 SR_SHA D5

Help

cnf matrix --help

HEC PRM

Run HEC-PRM related command

Commands

• Build
• Run
• Update Repo
• Show
• Debug

HEC-PRM build

Write HOBBES Network Format CALVIN data to dss file. Requires the Calvin HEC Runtime (see releases section)

Examples:

Basic

cnf hec-prm build --prefix out

Specify date range for TimeSeries data

cnf build --prefix partialRun --start 2000-01 --stop 2002-1

By default to files will be created in your current working directory. If you would like to specify the path to create the files, use the --output flag.

Help

cnf hec-prm build --help

HEC-PRM Run

Run the hecprm.exe program with provided prefix files from the build command. Wine is required.

cnf hec-prm run --prefix [prefix]

Help

cnf hec-prm run --help

HEC-PRM Update Repo

Apply flow results from HEC-PRM run back to CALVIN data repository.

cnf hec-prm update-repo --prefix [prefix]

Help

cnf hec-prm update-repo --help

HEC-PRM Show

Print a list of nodes as they are represented in the pri files. You can pass 'ALL' to print all nodes/links.

cnf hec-prm show ALL

Help

cnf hec-prm show --help

HEC-PRM Debug

Commands

• Show Build
• DSS to JSON

HEC-PRM Show Build

Print the JSON that will be passed to the DssWriter. Optional flag --showData will print the csv file data as well. Otherwise just the path is printed.

Example

cnf hec-prm debug show-build [node1] [node1] ...

Help

cnf hec-prm debug show-build --help

HEC-PRM DSS to JSON

Dump DSS file to directory. index.json file will contain all nodes by name. Each entry will then have a single json file representation in directory.

Example

cnf hec-prm debug dss-to-json -f [path/to/dss/file]

help

cnf hec-prm debug dss-to-json --help

Library

Run cnf maintenance related command

Commands

• Init
• Update

Library Init

Initialize the .prmconf file. Downloads runtime if needed.

Init will ask for your full path to the data repo's /data folder (/path/to/repo/calvin-network-data/data). Then it will download the runtime and create a .prmconf file in your home dir containing the path to both the runtime and the data repo so these do not need to be supplied every time you run a command.

cnf library init

Library Update

Update cnf and CALVIN HEC-PRM Runtime to latest versions.

cnf library update

Validate

Validate a CALVIN data is in HOBBES network format. Prints the errors and number of nodes, links and regions found.

Example:

cnf validate

Help

cnf validate --help

List

Print list of all nodes/links given as [Prmname],[Repo Path]. Pass 'ALL' to print all nodes/links.

Example:

cnf list [node1] [node2] ...

Help

cnf list --help

Apply Changes

Using the Calvin Network App (repo here), you can download all tabular data for a node/link in a single excel file using the 'Download Excel Data File' button. ex: https://cwn.casil.ucdavis.edu/#info/north-coast,lower-klamath,sr_cle.

Using this file you can make modifications to the underlying data for a node. Once you are ready to apply those modifications back to the data repo, you simply run this command passing the path to the excel file. You should be able to use git to make sure all changes were apply correctly to the data repo.

Example:

cnf apply-changes -x [path]

Help

cnf apply-changes --help

ADVANCED Stuff

.prmconf file

All arguments for prm commands can be passed via command line parameter or stored in a JSON formatted .prmconf file. This file should be stored in your accounts home directory be default. If you wish to supply a config file that is not located in your home directory, you can do so with --config [path/to/config/file] parameter.

Again, the quick start command above will configure this file for you.

Calvin HEC Runtime

Download the HEC Runtime

For your convenience and to reduce pain and suffering, we have created a package with all required libraries to run the cnf tool minus NodeJS (and wine). The package can be found here in the releases section.

Currently this runtime is REQUIRED to run the build command. You need to download and unzip the package. Then specify the path to the unzipped folder in build using the --runtime flag. Or you can simply run prm init and this will download and install the runtime as well as create a .prmconf file in your home folder.

The Runtime contains:

• Java 32-Bit
• HecDss Java Library
  • The required jars are bundled with HEC-DSSVUE
  • jars are found in /path/to/install/dir/HEC/HEC-DSSVue/lib;
• DssWriter.jar
• Custom csv to paired/timeseries data DSS writer java code
• HecPrm Executable

Linux / OS X

To use the Calvin HEC Runtime, wine is required for Linux and OS X.

• wine
  • Linux: use apt-get or other package manager
  • OS X: use homebrew
    • brew install wine

DSSVUE

You will most likely want to review your DSS files from time to time. HEC-DSSVue is the most common software for that. The download section of the HEC-DSSVue includes a windows and a linux version available for download.

For linux, if you have root access, consider unzipping the hec-dssvue201 directory int /usr/local/lib, and copying the hec-dssvue.sh file to /usr/local/bin/dssvue, with the proper modification of PROG_ROOT. This allows access to the program for all users. A few other minor tweaks seem to be required.
