Help, please.

What does this error message mean? 

C:\MetaQTL>java org.metaqtl.main.MetaDB -e expt.csv -m maps -d
markerDir.csv -o xml --mrkrm mrkrmAllInversions.txt

C:\MetaQTL>java org.metaqtl.main.InfoMap -m xml -o metaMap/infomapRev1
-t 2

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: -1

        at org.metaqtl.MapCluster.addAllMap(MapCluster.java:215)
        at org.metaqtl.main.InfoMap.main(InfoMap.java:127)

How might I solve this problem?

Thanks.
