Problems with using WebACT to create crunch files for ACT

I have been trying to create crunch files of two prokaryotic genome so I can compare both genomes using Artemis Comparison Tool (ACT). However, all my effort has been unsuccessful. I do not get any e-mail confirming that I have submitted a request or that my request has been processed. All I get whenever I use the link for my query is:

WebACT | Running Query WebACT Status You can either wait for the comparison to complete, or bookmark this link and return at a later date Results will be retained on the server for 7 days

I'll appreciate if anyone can help.

Thank you in advance.

Did you ever get your results? If so, how long did it take? I've submitted mine about 1.5 hours ago and didn't get a link or email either. My genomes are very small, so I wouldn't expect the program to have any issues with them.

Vlancl1, I eventually got a way out the mess created by WebAct and DoubleAct- In a terminal, I typed the following:

  1. sudo apt-get install ncbi-blast+ (to downloaded Blast)

  2. makeblastdb -in Genome1 -dbtype nucl

  3. blastn -query genome2 -db Genome1 -evalue 1 -task megablast -outfmt 6 > Genome1_Genome2.crunch

make sure you have the assembled genome that you want to compare in your working directory
