### Create synthetic data for TileFetcher example

Source: https://spacetx-starfish.readthedocs.io/en/latest/gallery/data_formatting/plot_format_tilefetcher.html

This code generates synthetic image tiles for the example. It creates two directories (primary_dir and nuclei_dir) and saves ten-by-ten pixel TIFF files for each combination of fov, round, channel, and z-plane. The script uses numpy, scikit-image, and tempfile, and prints low contrast warnings.

```python
import os
import numpy as np
import skimage.io
import tempfile

# columns: r, ch, zplane
fovs = [
    [
        (0, 0, 0),
        (0, 0, 1),
        (0, 0, 2),
        (1, 0, 0),
        (1, 0, 1),
        (1, 0, 2),
    ],
    [
        (0, 0, 0),
        (0, 0, 1),
        (0, 0, 2),
        (1, 0, 0),
        (1, 0, 1),
        (1, 0, 2),
    ],
]

data = np.zeros((10, 10), dtype=np.float32)

# create example image tiles that adhere to the structured data schema
inputdir = tempfile.TemporaryDirectory()
primary_dir = os.path.join(inputdir.name, "primary_dir")
nuclei_dir = os.path.join(inputdir.name, "nuclei_dir")
os.mkdir(primary_dir)
os.mkdir(nuclei_dir)

for fov_id, fov in enumerate(fovs):
    for round_label, ch_label, zplane_label in fov:
        primary_path = os.path.join(
            primary_dir, f"primary-f{fov_id}-r{round_label}-c{ch_label}-z{zplane_label}.tiff")
        nuclei_path = os.path.join(
            nuclei_dir, f"nuclei-f{fov_id}-r{round_label}-c{ch_label}-z{zplane_label}.tiff")
        skimage.io.imsave(primary_path, data)
        skimage.io.imsave(nuclei_path, data)

Shows how to view the multi-dimensional spot finding results interactively with napari. The code is commented out and requires uncommenting the lines and enabling the Qt GUI with %gui qt. It displays the cropped dots stack with each spot table.

```python
# uncomment to view with napari
# %gui qt
# BlobDetector
# viewer = display(stack=cropped_dots, spots=bd_table)

# LocalMaxPeakFinder

### Run write_experiment_json()

Source: https://spacetx-starfish.readthedocs.io/en/latest/gallery/data_formatting/plot_format_tilefetcher.html

This code calls write_experiment_json() with the required parameters: a TileFetcher instance, the output path, and a primary image dimension. It constructs the necessary parameters based on the fovs, rounds, channels, and zplanes of the example data.

```python
from starfish.experiment.builder import write_experiment_json

### Disable caching in ~/.starfish.config

Source: https://spacetx-starfish.readthedocs.io/en/latest/_modules/starfish/core/config.html

Example configuration file content to disable caching by setting the size_limit to 0.

```json
{
    "slicedimage": {
        "caching": {
            "size_limit": 0
        }
    }
}
```

### Set validation strict via JSON configuration

Source: https://spacetx-starfish.readthedocs.io/en/latest/help_and_reference/configuration/index.html

Example JSON configuration that sets strict validation to true.

```json
{
    "validation": {
        "strict": true
    }
}

```

### Clone Starfish repository and enter directory

Source: https://spacetx-starfish.readthedocs.io/en/latest/developer_guide/index.html

Clones the Starfish repository from GitHub and changes into the starfish directory. This is the first step in setting up a development environment.

```bash
$ git clone git://github.com/spacetx/starfish.git
$ cd starfish

```

### Visualize spots by accessing SpotAttributes and adding points to napari viewer

Source: https://spacetx-starfish.readthedocs.io/en/latest/gallery/how_to/assess_spotfindingresults.html

Shows how to add detected spots as points to a napari viewer using the SpotAttributes from the SpotFindingResults. The code is commented out and requires the %gui qt magic command to be uncommented. Since spots were found using a reference image, the SpotAttributes are the same for every ImageSlice.

```python
# uncomment code to view
# %gui qt
# viewer = display(stack=dots)
# viewer.add_points(data=spots[{Axes.CH:1, Axes.ROUND:0}].spot_attrs.data[['z', 'y',
# 'x']].to_numpy(), size=5)

### Apply Divide Function with Filter.Map

Source: https://spacetx-starfish.readthedocs.io/en/latest/api/image/index.html

This example shows how to use Filter.Map to apply a division operation to a synthetic image stack.

```python
>>> from starfish.core.imagestack.test.factories.synthetic_stack import synthetic_stack
>>> from starfish.image import Filter
>>> from starfish.types import Axes
>>> stack = synthetic_stack()
>>> divider = Filter.Map("divide", 4)
>>> by_four = divider.run(stack)
```
