I am not a programmer so maybe my question seem very fundamental. I have to run the the code in the link below to get an output file: https://github.com/matsim-org/pt2matsim/blob/master/src/main/java/org/matsim/pt2matsim/run/Gtfs2TransitSchedule.java
This code gets an input (a folder containing some text files related to open street map) and also in the code I have to specify a coordinate system (in my case is EPSG:3857) and I think also I have to specify a path fot the output file. Unfotunately I don't know how I should specify the input file and also how I should edit my desired coordinate system. Also I have to mention these are written as args[0], args[1], args[2] and args[4] in the code.
