# GPXanalysis
Analysis of GPX tracks using IgorPro
## GPXSimilarPaths
A workflow to find and compare similar running routes from a large database.
The inspiration is the Strava feature that allows runners to compare performance over the same course over time.
Starting point is a long gpx/xml output containing multiple tracks (tested on ~700 tracks).
The file is processed using `GPX2CSVwithTrackeR.R` to give a csv called `runDF.csv`.
This file is read by `GPXSimilarPaths.ipf`.
Igor parses all the tracks and compares them to find clusters of similar tracks.
For each cluster, a comparison of pace is done.
## GPX2Igor
Requires XMLUtiles XOP for Igor, available [here](http://www.igorexchange.com/project/XMLutils).
These functions will load and parse a directory of gpx files. Igor will plot out all the tracks and also allow you to pick an interval to make a movie of tracks in that period. It will export a movie (`*.mov` with jpeg compression) and a sequence of TIFFs at 4X screen resolution (this is so you can assemble a `*.gif` version).
Now there are versions for looking at Running and Cycling. The running analysis is tested only on GPX tracks exported from rubitrack and recorded using a Garmin watch. Export was automated using `Rubitrack Export.scpt`. This is an applescript which runs from the Users Scripts folder and works with card view in rubiTrack 4 Pro. The cycling analysis is quite bespoke (sorry) and requires an external procedure to run properly.
## CumulativeTime
Rubitrack can output a single GPX file with multiple tracks. This can be read into R and then the cumulative time per year calculated using IGOR. To read in the GPX file use `GPX2CSV.R`
