napari_bigfish.bigfishapp module

class napari_bigfish.bigfishapp.BigfishApp[source]

Bases: QObject

Application model for the napari FISH-spot detection widget, that runs the bigfish gaussian background correction and spot detection.

alphaSignal[source]
betaSignal[source]
countSpotsPerCellAndEnvironment(cytoplasmLabels, nucleiLabels)[source]

Counts the number of spots in the image and stores it in the attribute nrOfCells. Creates the cellLabelOfSpot list, that contains the cell-label for each spot and the nucleiLabelOfSpot list, that contains True for all spots that are within a nucleus.

Parameters:
  • cytoplasmLabels (numpy.ndarray) – The cell-labels

  • nucleiLabels (numpy.ndarray) – The nuclei-mask or labels

createEmptySpotCountReport(inputPath)[source]

Create a csv-file, containing only the column headings, for the spot-count-report and return the path to the file. The file is written into a subfolder results of the input folder.

Parameters:

inputPath – The path to an input image

deactivateFindThreshold()[source]
deactivateRemoveDuplicates()[source]
decomposeDenseRegions(scale)[source]

Run the decomposition of the dense regions.

Parameters:

scale (2 or 3-tupel of float) – The scale (voxel size) of the image in the z, y and x dimensions in nm.

decomposeRadiusSignal[source]
detectSpots(scale)[source]

Run the spot detection step with or without automatic threshold detection.

Parameters:

scale (2 or 3-tupel of float) – The scale (voxel size) of the image in the z, y and x dimensions in nm.

getData()[source]
getDecomposeRadiusXY()[source]
getDecomposeRadiusZ()[source]
getDecomposeSpotRadius()[source]

Answer the spot radius for the decomposition of dense regions.

Return type:

2 or 3-tupel of float

getGamma()[source]
getRadiusXY()[source]
getRadiusZ()[source]
getResult()[source]
getScale(scale)[source]

Answer the scale (voxel-size) in nm in the different dimensions

Return type:

2 or 3-tupel of float

getSigmaXY()[source]
getSigmaZ()[source]
getSpotCountPerCellAndEnvironment()[source]

Returns a table containing the spot-count for each cell, with the number of cells within the nucleus, outside of the nucleus and the total number.

Return type:

list of lists

getSpotRadius()[source]

Return the spot radius in the z, y and x-dimension

Return type:

2 or 3-tupel of float

removeDuplicatesSignal[source]
reportSpotCounts(inputPath, outputPath)[source]

Write a csv-file with the spot-counts.

Parameters:
  • inputPath – The path of the input image will be reported in the csv-file

  • outputPath – The directory into which the csv-file will be written

reportSpots(inputPath)[source]

Write a csv-file with the coordinates of the detected spots. The file can be opened by napari as a points-layer.

Parameters:

inputPath – The past to the input images; the file will be written into a subdirectory “spots” of that directory.

runBatch(scale, inputImages, cellLabels=None, nucleiMasks=None, subtractBackground=False, decomposeDenseRegions=False)[source]

Run the processing in batch-mode on the input images.

Parameters:
  • scale (3-tupel of floats) – A tupel with the scales (voxel-sizes) of the images in nm for the z, y and x dimensions

  • inputImages – A list of paths to the input images

  • cellLabels – An optional list of paths to the cell label images

  • nucleiMasks – An optional list of paths to the nuclei mask images

  • subtractBackground – A boolean telling wether to subtract the background before the analysis

  • decomposeDenseRegion – A boolean telling wether to decompose dense regions for the spot detection
