StrokeCommandLine

This is a simple command line interface to StrokeModel. Run with no arguments to run an example scenario, or use command line flags to modify inputs. Arguments are processed by ArgParse.

Usage

The following settings are available via the given command line arguments:

• Run base case only: --base_case -b (Single run using median intra-hospital times)
• Model iterations: --iterations -i (Default: 1000)
• Sex: --male -m or --female -f (Default: Female)
• Age: --age -a ## (Default 70)
• Stroke severity: --race -r ## or --nihss ## (Default: RACE 3)
• Time from symptom onset: --symptom_time --sym -s ## (Default: 30 minutes)
• Travel times (each can be entered multiple times, with the flag included each time):
  • Primary: --primary_time --prim -p ## (Default: [25, 30, 45])
  • Transfer (paired with primaries): --transfer_time --trans -t ## (Default: [50, 35, 20])
  • Comprehensive: --comprehensive_time --comp -c ## (Default: [60])

Use the flag --help to print a description of the options.

Travel times

Note that currently only the closest primary and comprehensive center will be used for strategies other than drip-and-ship. Multiple comprehensive times are accepted for future compatibility with center-specific performance distributions. When entering multiple primary centers, each must have an accompanying transfer time, and these pairs will be formed in the order the arguments are provided.

Examples

For a 50 year old male with RACE 4 and only potential primary center 14 minutes away followed by a 60 minute transfer to a comprehensive center with the nearest comprehensive center 55 minutes from the site of the stroke, you could run

StrokeCommandLine -m -r 4 -p 14 -t 60 -c 55

If there are two potential primary centers, one 15 minutes away followed by a 75 minute transfer and another 35 minutes away with a 30 minute transfer, you can indicate this with:

StrokeCommandLine -p 15 -t 75 -p 35 -t 30

In the printed results, the first primary center will be Primary 0 in drip and ship strategies and the second will be Primary 1. The order of arguments does not matter except for multiple arguments for primary and transfer times.

Installation

With Swift 4.1 or higher installed, running swift build -c release in the root directory of the repository will create an executable at .build/release/StrokeCommandLine. This should work on macOS or Linux, with the caveat that the Linux version is single-threaded due to some instability with Grand Central Dispatch on Linux. If you have problems with this, running swift package update may fix some dependency issues.
