java.lang.NullPointerException error in IGVtools when trying to Find Motif

Question

[michael.nagle]

I am running the latest version of IGVtools and have several .fa files loaded. I am now trying to locate a particular motif in these files. I start with Tools -> Find Motif, enter the sequence, then get this error. How should I go about resolving this? Thanks
