Dear Galaxy,
I am trying to import a multiz alignment file for all the insect species from the UCSC genome browser. Galaxy does not recognize number of blocks in the multiz file as there is a question mark in the file format view (? blocks). Then when I am trying to use the tool ( Extract MAF blockshttps://usegalaxy.org/tool_runner?tool_id=Interval2Maf1given a set of genomic intervals) then there is an error saying
"An error occurred with this dataset:191757 MAF blocks converted to Genomic Intervals for species dm3. There was a problem processing your input: exceptions must be old-style classes or derived from BaseException, not str" and even when the tool runs it shows the following message " This is a new dataset and not all of its data are available yet "
Please look into the problem.
warm regards, Amit.
