+This Dataset is part of [The Well Collection](https://huggingface.co/papers/2412.00568).
+
+# How To Load from HuggingFace Hub
+
+1. Be sure to have `the_well` installed (`pip install the_well`)
+2. Use the `WellDataModule` to retrieve data as follows:
+
+```python
+from the_well.data import WellDataModule
+
+# The following line may take a couple of minutes to instantiate the datamodule
+datamodule = WellDataModule(
+    "hf://datasets/polymathic-ai/",
+    "gray_scott_reaction_diffusion",
+)
+train_dataloader = datamodule.train_dataloader()
+
+for batch in dataloader:
+    # Process training batch
+    ...
+```
+
+# Pattern formation in the Gray-Scott reaction-diffusion equations
+
+**One line description of the data:** Stable Turing patterns emerge from randomness, with drastic qualitative differences in pattern dynamics depending on the equation parameters.
+
+**Longer description of the data:** The Gray-Scott equations are a set of coupled reaction-diffusion equations describing two chemical species, \\(A\\) and \\(B\\), whose concentrations vary in space and time. The two parameters \\(f\\) and \\(k\\) control the “feed” and “kill” rates in the reaction. A zoo of qualitatively different static and dynamic patterns in the solutions are possible depending on these two parameters. There is a rich landscape of pattern formation hidden in these equations.
+
+**Associated paper**: None.
+
+**Domain expert**: [Daniel Fortunato](https://danfortunato.com/), CCM and CCB, Flatiron Institute.
+
+**Code or software used to generate the data**: [Github repository](https://github.com/danfortunato/spectral-gray-scott) (MATLAB R2023a, using the stiff PDE integrator implemented in Chebfun. The Fourier spectral method is used in space (with nonlinear terms evaluated pseudospectrally), and the exponential time-differencing fourth-order Runge-Kutta scheme (ETDRK4) is used in time.)
+
+**Equation describing the data**
+
+$$
+\begin{align*}
+\frac{\partial A}{\partial t} &= \delta_A\Delta A - AB^2 + f(1-A) \\ \frac{\partial B}{\partial t} &= \delta_B\Delta B - AB^2 - (f+k)B
+\end{align*}
+$$
+
+The dimensionless parameters describing the behavior are: \\(f\\) the rate at which \\(A\\) is replenished (feed rate), \\(k\\) the rate at which \\(B\\) is removed from the system, and  \\(\delta_A, \delta_B\\) the diffusion coefficients of both species.

+## About the data
+
+**Dimension of discretized data:** 1001 time-steps of 128 \\(\times\\) 128 images.
+
+**Fields available in the data:** The concentration of two chemical species \\(A\\) and \\(B\\).
+
+**Number of trajectories:** 6 sets of parameters, 200 initial conditions per set = 1200.
+
+**Estimated size of the ensemble of all simulations:** 153.8 GB.
+
+**Grid type:** uniform, cartesian coordinates.
+
+**Initial conditions:** Two types of initial conditions generated: random Fourier series and random clusters of Gaussians.
+
+**Boundary conditions:** periodic.
+
+**Simulation time-step:** 1 second.
+
+**Data are stored separated by (\\(\Delta t\\)):** 10 seconds.
+
+**Total time range (\\(t_{min}\\) to \\(t_{max}\\)):** \\(t_{min} =0\\), \\(t_{max} = 10,000\\).
+
+**Spatial domain size (\\(L_x\\), \\(L_y\\)):** \\([-1,1]\times[-1,1]\\).
+
+**Set of coefficients or non-dimensional parameters evaluated:** All simulations used \\(\delta_u = 2.10^{-5}\\) and \\(\delta_v = 1.10^{-5}\\).
+"Gliders": \\(f = 0.014, k = 0.054\\). "Bubbles": \\(f = 0.098, k =0.057\\). "Maze": \\(f= 0.029, k = 0.057\\). "Worms": \\(f= 0.058, k = 0.065\\). "Spirals": \\(f=0.018, k = 0.051\\). "Spots": \\(f= 0.03, k=0.062\\).
+
+**Approximate time to generate the data:** 5.5 hours per set of parameters, 33 hours total.
+
+**Hardware used to generate the data:** 40 CPU cores.
+
+## What is interesting and challenging about the data:
+
+**What phenomena of physical interest are catpured in the data:** Pattern formation: by sweeping the two parameters \\(f\\) and \\(k\\), a multitude of steady and dynamic patterns can form from random initial conditions.
+
+**How to evaluate a new simulator operating in this space:** It would be impressive if a simulator—trained only on some of the patterns produced by a subset of the \\((f, k)\\) parameter space—could perform well on an unseen set of parameter values \\((f, k)\\) that produce fundamentally different patterns. Stability for steady-state patterns over long rollout times would also be impressive.
+
+
+**Warning:** Due to the nature of the problem and the possibility to reach an equilibrium for certain values of the kill and feed parameters, a constant stationary behavior can be reached. Here are the trajectories for which a stationary behavior was identified for specy \\(A\\) as well as the corresponding time at which it was reached:
