Hi Jim, You'll need to update your datatypes_conf.xml file to get custom builds + converters to work. This file is located in the root of your galaxy directory. If you haven't modified your datatypes_conf.xml file previously, you can just copy datatypes_conf.xml.sample to datatypes_conf.xml If you have modifed this file, please add the following lines to your datatypes_conf.xml: (a) <converter file="fasta_to_2bit.xml" target_datatype="twobit"/> <converter file="fasta_to_len.xml" target_datatype="len"/> to the fasta definition and (b) <converter file="len_to_linecount.xml" target_datatype="linecount"/> to the len definition See datatypes_conf.xml.sample for examples. Also, you'll need to download and add the UCSC program fastaToTwoBit to your path as well. You can find UCSC executables here: hgwdev.cse.ucsc.edu/~kent/exe/ Good luck, J.

Hello,

I've tried to create a custom build (starting from the trackster page) and clearly made some mistake. I get a NoConverterException error which is almost certainly my fault putting something wrong in. However, now the Custom Builds page shows this error and I cannot make it go away.

I have a local install, have killed and restarted, logged in and out, but still this error stays. I cannot try to enter another custom build because there is nothing on the page except this error. Does anyone kow how to get rid of this? Any help in getting around this error are appreciated.
