The input for this script is a mapping file and the name of a column, it has to be numeric, from which a distance matrix will be created. The output of this script is a distance matrix containing a dissimilarity value for each pairwise comparison.
As this is a univariate procedure only one metric is supported: d = c-b.
Usage: distance_matrix_from_mapping.py [options]
The output of distance_matrix_from_mapping.py is a file containing a distance matrix between rows corresponding to a pair of columns in a mapping file.
To calculate the distance matrix (using euclidean distance) on a column of the mapping file, where the results are output to DOB.txt, use the following command:
distance_matrix_from_mapping.py -i Fasting_Map.txt -c DOB
Pairwise dissimilarity using the Vincenty formula for distance between two Latitude/Longitude points:
To calculate the distance matrix (using Vincenty formula) on a column of the mapping file, where the results are output to lat_long.txt, use the following command:
distance_matrix_from_mapping.py -i lat_long.txt -c Latitute,Longitude -o lat_long_dtx_matrix.txt
