# Available tools
To access your image data, you can always upload it to your history. However, since the images are usually heavy, there are connectors to existing public databases that will bring the data that you need into Galaxy.
TOOL | DESCRIPTION |
---|---|
IDR/OMERO Download Tool | Access to public images at the IDR. This tool allows access to image data in private OMERO instances. |
Convert image | Tool to convert image formats. |
{: .table.table-striped} |
There are many tools organised into suites to segment and extract features from your images.
TOOL | DESCRIPTION |
---|---|
CellProfiler Suite | CellProfiler modules available: Starting Modules (Images, Metadata, NamesAndTypes, Groups), IdentifyPrimaryObjects, OverlayOutlines, ImageMath, TrackObjects, DisplayDataOnImage, ColorToGray, GrayToColor, Tile, ConvertObjectsToImage, RelateObjects, MeasureImageIntensity, MeasureObjectIntensity, MeasureGranularity, MeasureTexture, MeasureImageAreaOccupied, MeasureImageQuality, MaskImage, MeasureObjectSizeShape, Export to Spreadsheet, EnhanceOrSuppressFeatures, SaveImages. Every workflow needs to start by Starting Modules and end by CellProfiler. The last tool takes two inputs: an image collection and a CellProfiler pipeline (assembled in previous steps of the workflow). |
ImageJ Suite | Several plugins are available in Galaxy: Add shadow effect, Analyze skeleton, Watershed segmentation, Adjust threshold, Convert binary image to EDM, Skeletonize, Analyze particles, Operate on pixels, Add or remove noise, Find maxima, Convert to binary, Enhance contrast, Create new image, Sharpen, Find edges, Smooth. |
bUnwarpJ (ImageJ) | Apply raw transformation, Convert elastic transformation to raw, Apply elastic transformation, Compare elastic and raw deformation, Align two images, Compare opposite elastic deformations, Compose two raw transformations, Compare two raw deformations, Compose two elastic transformations, Compose a raw and an elastic transformation, Adapt an elastic transformation. |

The imaging flavour of Galaxy is a joint effort between different partners including EOSC-Life and its associated Research Infrasctuctures (Euro-Bioimaging, ELIXIR), and the University of Freiburg{:target="_blank"}.
The service is part of the European Galaxy server and is maintained by the RNA Bioinformatics Center (RBC){:target="_blank"} as part of de.NBI{:target="_blank"} and ELIXIR{:target="_blank"}.
