Download image data from the IDR_ (Image Data Resource) - a public repository
of reference image datasets from published scientific studies.

.. _IDR: https://idr.openmicroscopy.org/about/

-----

.. class:: infomark

**Input**

A set of image IDs as can be obtained from the IDR webclient_ like this:

1. Select the wells you want to download in the thumbnails.

2. Select at the bottom the images in those wells that you want to download (one well might contain several images).

3. Click on the 'Link' button on the top right of the page and copy the provided URL.

4. Paste the URL into the input field of this tool, for example:

    https://idr.openmicroscopy.org/webclient/?show=image-9036708|image-9036710|image-9036711

Alternatively, you can simply provide a list of known image IDs in the text
input field (comma or '|'-separated ), or as an input file (each ID on a
separate line).

Finally, if you want to download all images of a single dataset. Specify the id as 
All images from a single Dataset ID.

Most images in the IDR have more than two dimensions. Thus, there are
parameters available which allow you to select a particular recording channel,
z-plane or time frame to download.
You can also select a region which will be used to crop the images, rather
than downloading the entire file.

**Output**

Downloaded images will be saved in TIFF format. If you selected multiple image
IDs to download, these will be saved as elements of a collection.

The accompanying error log dataset may hold valuable information about requests
that could not be fulfilled exactly as specified, or that were found to be
ambiguous.
