MRI_Opera_export_tools
The tool stitches images from the Opera Phenix HCS System. It reads the Index.idx.xml
file to pre-arrange the images and then stitches and fuses them using the Grid/Collection stitching
-plugin [1]. Images are stitched by plane and channel. Z-stacks and multi-channel images can optionally be created. Projections can also be created.
The source code in git-hub can be found here.
To install the tool save the files opera_export_tools.ijm and opera_export_tools.py into the folder macros/toolsets of your FIJI installation. To use the Pseudo flat-field correction you need to have the biovoxxel-toolbox installed.
Select the "opera_export_tools" toolset from the >> button of the ImageJ launcher.
- the first button opens this help page
- second button allows to select the index-file
- the third button allows to select the wells, that will be exported
- the fourth button allows to rename the wells (Optional)
- the fifth button allows to modify the export options
- the sixth button allows to modify the correction options (Optional)
- the seventh button starts the batch-export
Press the Set index-file
-button and select the folder containing the images and the index file Index.idx.xml
.
The path must not contain space or special characters such as accents. If necessary rename folders before selecting the index-file!
Press the Select wells
-button and select the wells you want to export. If export all
is selected, all wells will be exported.
Press the Rename wells
-button and change the names of the wells. Well names will be saved and can be loaded from a wellNames.txt
file
You can set the names of the wells automatically from a spreadsheet using Opera_Wellnames_from_CSV
Press Set options
-button.
- Base for stitching
- Z-Slice / Max Intensity Projection
- Select if the stitching is calculated from a z-slice or from a projection of each slices
- z-slice for stitching
- The z-slice used to calculate the stitching. Enter 0 to use the middle slice. (Not used if Max intensity Projection is selected)
- channel for stitching
- The channel, that is used to calculate the stitching
- Fusion parameters
- The parameters for the stitching plugin [1]
- Export Options
- Export Z-Stack of Fields
- If selected will create a folder containing the Z-Stack.
- Export Projection of Fields
- If selected will create a folder containing the max intensity projection of each slices.
- Export Z-Stack of Mosaics
- If selected will create a folder containing the mosaics as a Z-Stack.
- Export Projection of Mosaics
- If selected will create a folder containing the mosaics as a max intensity projection of each slices.
- + Composite
- When doing an export, also create a multi-channel composite image.
- RGB of Projection of Mosaics
- If selected will create a folder containing RGB images of the mosaics' projection.
- Invert and export individual channel
- If selected will create a folder containing inverted images of individual channels of the mosaics' projection.
- Export Colours
- Set the colours for each channels.
- Export Bounds
- Set the bounds for each channels for RGB and individual channel export.
Press Set correction options
-button.
- Image correction/normalization
- normalize
- If selected the the intensities of the tiles of a mosaic are normalized.
- pseudo flat field radius
- The radius for the pseudo flat field correction. Set the radius to 0 if you do not want to apply a pseudo flat field correction. You must have the biovoxxel toolbox [2] installed
- rolling ball radius
- The radius for the rolling-ball background correction. Set the radius to 0 if you do not want to apply a rolling-ball background correction.
- find background radius
- The radius for the find and subtract background operation. Set the radius to 0 if you do not want to apply the find and subtract background operation.
Press the Launch export
-button to start the batch export of the images.
The resulting images will be written into the parent folder of the folder containing the index-file.
Z-Stack of fields will be in the stack
folder
Max intensity projection of fields will be in the projection

Z-Stack of mosaics will be in the stackMosaic

An options file will also be written (YYYY-MM-DD_HH_MM_SS_options.txt)
it contains the informations about your execution.
- 03.09.2024 - The tool now handles both formats, the format of harmony 5 and the format of harmony 6.
