List of features extracted for the purpose of predicting lymph node metastases type. Features were extracted after thresholding tumour probability heatmaps. For feature numbers 5, 6, 7, 8 and 9 the following statistics were computed- maximum, mean, variance, skewness, and kurtosis.

No.	Feature description	Threshold (p)
1	Largest tumour region’s major axis length	$p=0.9$ & $p=0.5$
2	Largest tumour region’s area	$p=0.5$
3	Ratio of tumour region to tissue region	$p=0.9$
4	Count of non-zero pixels	$p=0.9$
5	Tumour regions area	$p=0.9$
6	Tumour regions perimeter	$p=0.9$
7	Tumour regions eccentricity	$p=0.9$
8	Tumour regions extent	$p=0.9$
9	Tumour regions solidity	$p=0.9$
10	Mean of all region’s mean confidence probability	$p=0.9$
11	Number of connected regions	$p=0.9$
