msi.dataset-class object |
refImage |
ms.image-class object. Image used as reference to manually select the ROI pixels. |
mzQuery |
numeric. Values of m/z used to calculate the reference image.
2 values are interpreted as interval, multiple or single values are searched
in the m/z vector. It overrides |

useFullMZ |
logical (default = 'TRUE“). Whether all the peaks should be used to perform the supervised segmentation. |
method |
string (default = 'svm'). Supervised classifier used to segment the ROI. |
verbose |
boolean (default = 'TRUE'). Additional output. |
ms.image-class object representing the binary mask image.
