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 blocks given 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.
