MaximumMatchingAccuracy Index out of Bounds Exception #80

Hey, im new to elki and might be doing something wrong. When i run: for k in $( seq 3 40 ); do java -jar elki-bundle-0.7.6-SNAPSHOT.jar KDDCLIApplication -dbc.in data/synthetic/Vorlesung/mouse.csv -algorithm clustering.kmeans.LloydKMeans -kmeans.k $k -resulthandler ResultWriter -out.gzip -out output/k-$k ; done i get a lot of

if i do for k in $(seq 3 6) it works. When i go from 6 to 7 or 40 as above it starts to throw the exceptions.

Thanks for reporting, fixed. Not in k-means, but in a fairly new evaluation class. If you used the maximum matching results anywhere, you may want to rerun them.
