This guide will show you how to use VFBconnect to download images from the Virtual Fly Brain (VFB) based on a dataset. | ||
--- | ||
|
||
## Introduction | ||
|
||
VFBconnect is a Python package that provides an interface to the Virtual Fly Brain (VFB) API. It allows users to query the VFB database and download data, including images. | ||
|
||
## Installation | ||
|
||
Before you can use VFBconnect, you need to install it. You can do this using pip: | ||
|
||
\`\`\`bash | ||
pip install vfb-connect | ||
\`\`\` | ||
|
||
## Downloading Images | ||
|
||
To download images from VFB using VFBconnect, you need to first import the package and create a client: | ||
|
||
\`\`\`python | ||
from vfb_connect.cross_server_tools import VfbConnect | ||
vc = VfbConnect() | ||
\`\`\` | ||
|
||
Next, you can use the `get_images` method to download images. This method requires the dataset ID as an argument: | ||
|
||
\`\`\`python | ||
dataset_id = 'your_dataset_id' | ||
images = vc.get_images(dataset_id) | ||
\`\`\` | ||
|
||
This will return a list of images from the specified dataset. Each image is represented as a dictionary with information such as the image ID, title, and URL. | ||
|
||
To download the images, you can loop through the list and use the `urlretrieve` function from the `urllib.request` module: | ||
|
||
\`\`\`python | ||
import urllib.request | ||
|
||
for image in images: | ||
url = image['image_url'] | ||
filename = image['image_id'] + '.jpg' | ||
urllib.request.urlretrieve(url, filename) | ||
\`\`\` | ||
|
||
This will download each image and save it as a JPEG file in the current directory. The filename is the image ID. | ||
|
||
## Conclusion | ||
|
||
This guide showed you how to use VFBconnect to download images from the Virtual Fly Brain based on a dataset. With VFBconnect, you can easily access and download data from VFB for your research. |
