Dear Anton,
Thank you for using the UCSC Genome Browser and your question about an error message when using liftOver.
Could you please provide some lines of the input file (foobar.bed) you are using. If the contents of '***' is representative of the file information for the blocksizes column, it could be your input file is incorrectly formatted as '***' is not a valid integer. You can send your data directly to me or to our private list at
genom...@soe.ucsc.edu.
