Cannot find the output file

[iggisv9t]

hdbscan/src/hdbscanTime.cpp

Lines 39 to 45 in 0f21522

	int main(int argc, char* argv[]) {
	//commandLine P(argc,argv,"[-o <outFile>] [-r <rounds>] [-p <0/1 perturb points>] <inFile>");
	commandLine P(argc,argv,"[-m <minPts value>] <inFile>");
	char* iFile = P.getArgument(0);
	size_t minPts = P.getOptionIntValue("-m",1);
	char* oFile = P.getOptionValue("-o");

As I understood those lines, there is no default value for the output file path, so I try to run hdbscan like this:

./hdbscan -m 5 -o ~/projects/hdbscan_out.csv ~/projects/hdbscan_inp.csv

It logs some info in the terminal, but I cannot find any output file.

Hi, sorry about the confusion. Currently the program does not support writing the output to disk. There are other ways to interpret the output:

1. Use it directly from our C++ API: https://github.com/wangyiqiu/hdbscan/blob/main/include/hdbscan/hdbscan.h
   Specifically, the two API functions output either the MST or the root node of the dendrogram, from which you could use in your own program. You could also try to output these results to the disk in a format that you like.

2. You can use our Python binding to generate a dendrogram that can be plotted directly in Python. See here: https://github.com/wangyiqiu/hdbscan#option-2-use-the-python-binding

I hope this helps. Let me know if you have more questions.

Thank you. It was not obvious to me, because I don't know C++. I'll try Python bindings.
