Re: problem with dreme output motif logos

[James Johnson]

Hi Fel,

What web browser are you using to view the output? Some older web browsers (Internet Explorer version 8 and lower is the most common) don't display images generated by Javascript on canvas. With DREME and some of the older programs you can specify the option "-png" and it will create generate actual images that Internet Explorer 8 can display.

Alternatively you may have encountered a bug in DREME. In that case I encourage you to send the output to the MEME support email me...@nbcr.net (or attach it here).

Hi James:

Thank you for the quick response. I do use -png option and get the png files. However, some of the png files are blank, see below, while some are correct.

Hi Fei,

That's probably caused by ImageMagick and you may have to install a newer version of either Ghostscript or ImageMagick and reconfigure your MEME installation to fix the problem.

There is a post here: https://groups.google.com/forum/#!searchin/meme-suite/convert/meme-suite/_2yqxZGyYa4/jhfINfPoL9gJ that gives more information.
