[galaxy-user] galaxy on the cloud - cannot select fastq files when trying to run workflow

Hi Galaxy,

I am a newbie to Amazon EC2 and have been carefully following the steps in the screencast. I am able to upload two fastq files from the s3 bucket: http://s3.amazonaws.com/heteroplasmy/F4-bM4-1.fastq http://s3.amazonaws.com/heteroplasmy/F4-bM4-2.fastq

I am also able import the published workflow http://s3.amazonaws.com/heteroplasmy/Galaxy-Workflow-mt_analysis_0.01_strand...

But when it comes to running it, I cannot select the fastq file from the drop down menu. I am able to view them on my GC instance, since I imported them successfully, but am at a loss as to why I can't select them from the drop down menu in the workflow to begin their alignment. Is it something to do with my security group settings in setting up the EC2 instance? Any assistance you can provide would be great!

Thanks, Amit
