Hello,
We are working on segmenting nuclei and tissue regions from histology slides. We would like to use CPA to create manually labeled training sets on both of these (so cells could be subtype 1, 2, 3, etc., and tissue regions could be of subtypes a, b, c, etc.), because CPA’s drag-and-drop-into-bins functionality is really convenient. However, when I create a single object table, CPA seems to arbitrarily choose one object type (either nuclei or tissue) to display, and shows no thumbnails of the other object type. To get around this, I created one table for each object, and manually changed the properties file to read from one or the other object type. This seems to be working fine, but is there a better solution?
In CPA, when I click on save training set, I obtain a file which reads something like
label positive negative
positive 1 83 1192 606
positive 2 108 865 537
positive 2 43 730 230
positive 2 1 119 9
positive 2 164 876 903
negative 2 148 357 767
negative 1 23 622 200
Could you explain what the different columns mean, please? Also, since my objects come from two different types (tissue and nuclei), will there be an overlap in object ID? I would like to extract out the relevant measures for each object in the training set, so that we can construct our own classifiers for them.
Thank you very much!
