I now have a different problem with a different (production) version of galaxy trickster.

I always get this message “Could not load chroms for this dbkey”

I have checked that I have files with the [key].len in tool-data/shared/ucsc/chrom and I have twobit files etc.

The weird thing is, that the “Create visualization” shows the genome keys I have but this window shows nothing for the dbkey it things it should be getting…

So somewhere it “looses” the key…

Any ideas?

(I’m running the latest update)

Thanks Jeremy,

I did what you suggested and now it no longer complains!

Not sure if I had edited datatypes_conf.xml but just copying the sample worked and let’s just hope I did not break any of my changes

Am I missing a converter?

Yes, you are missing the bed_to_bigwig converter. 

If you haven't made changes to your datatypes_conf.xml file, you can just copy datatypes_conf.xml.sample to datatypes_conf.xml to get the needed converters. 

If you've made changes to datatypes_conf.xml, you'll need to manually add the needed converters. We recently transitioned all the *_to_summary_tree converters to *_to_bigwig, so you'll want to remove the summary_tree converters and replace them with the bigwig converters.

And why would a BED file even needed to be converted?

Converter = indexer for visualizations. Datasets are indexed so that (a) aggregate (coverage) data is readily available when viewing a large region and (b) finding features in a small region (when zoomed in) is fast.
