csPredict
Short Description
The function csPredict
is employed to make predictions about the
expression of a specified marker on cells in new images using the models
generated by csTrain
. This calculation is done at the pixel level,
resulting in an output image where the number of channels corresponds to
the number of models applied to the input image. The parameter markerChannelMapPath
is used to associate the image channel number with the relevant model to be applied.
Function¶
csPredict(imagePath, csModelPath, projectDir, markerChannelMapPath, markerColumnName='marker', channelColumnName='channel', modelColumnName='cspotmodel', verbose=True, GPU=-1, dsFactor=1)

Parameters:
Name | Type | Description | Default |
---|---|---|---|
imagePath |
str
|
The path to the .tif file that needs to be processed. |
required |
csModelPath |
str
|
The path to the |
required |
projectDir |
str
|
The path to the output directory where the processed images ( |
required |
markerChannelMapPath |
str
|
The path to the marker panel list, which contains information about the markers used in the image. |
required |
markerColumnName |
str
|
The name of the column in the marker panel list that contains the marker names. |
'marker'
|
channelColumnName |
str
|
The name of the column in the marker panel list that contains the channel names. |
'channel'
|
modelColumnName |
str
|
The name of the column in the marker panel list that contains the model names. |
'cspotmodel'
|
verbose |
bool
|
If True, print detailed information about the process to the console. |
True
|
GPU |
int
|
An optional argument to explicitly select the GPU to use. The default value is -1, meaning that the GPU will be selected automatically. |
-1
|
dsFactor |
float
|
An optional argument to downsample image before inference. The default value is 1, meaning that the image is not downsampled. Use it to modify image pixel size to match training data in the model. |

Example
# Path to all the files that are necessary files for running csPredict
projectDir = '/Users/aj/Documents/cspotExampleData'
# csPredict related paths
imagePath = projectDir + '/image/exampleImage.tif'
markerChannelMapPath = projectDir + '/markers.csv'
csModelPath = projectDir + '/manuscriptModels/'
# Run the function
cs.csPredict( imagePath=imagePath,
csModelPath=csModelPath,
projectDir=projectDir,
markerChannelMapPath=markerChannelMapPath,
markerColumnName='marker',
channelColumnName='channel',
modelColumnName='cspotmodel')
# Same function if the user wants to run it via Command Line Interface
python csPredict.py --imagePath /Users/aj/Documents/cspotExampleData/image/exampleImage.tif --csModelPath /Users/aj/Documents/cspotExampleData/manuscriptModels --projectDir /Users/aj/Documents/cspotExampleData --markerChannelMapPath /Users/aj/Documents/cspotExampleData/markers.csv
