During HARMONY 2023, I've started experimenting with emscripten. This is a first test, getting COPASI to work. Simply upload a COPASI file and have it run (it will run a time course simulation). Experimentally some basic processing changes can be made, like changing durations or changing the simulation method.

Upload SBML / COPASI file

Some examples so that i can try it on a phone

Brusselator | MAPK-HF96-layout.cps (this one takes a while) | DimericMWC-stiff.cps

show cps show yaml

CPS Model:

Processing: Changes for processing in yaml for the problem:

{"problem":{"Duration": 100, "StepNumber": 100, "StepSize": 0.1}}

{"method": {"name": "Stochastic (Gibson + Bruck)"}}

or for changes of initialvalues in the form of display names. So:

```
[A]_0
```
for initial concentration of species A
```
Values[t].InitialValue
```
for initial value of parameter t
```
(r1).k
```
for the value of k of reaction r1.

{"initial_values": {"[A]_0": 10.0, "Values[t].InitialValue": 0.1, "(r1).k": 0.1}}
