I performed a MEGABLAST analysis a few days ago, but I am now unable to automatically retrieve organism names. The Megablast output file contains GI numbers, but no name of the organisms. I have now been trying to automatically get the names of the organisms identified with the Megablast for several days but I can't do it. 2 months ago I was said to use Fetch taxonomic representation tool during a Workshop on metagenomic analyzes, but I can't find this tool now. I was then said to use Kraken, I tried to use it but I couldn't because no option is available to select database. Am I doing something wrong? Then, somebody told me to use testgalaxyproject.org and I found the Fetch Taxonomic Represntation tool in the section Old Metagenomics. Is this tool obsolete or why does it not appear in usegalaxy.org? What is the difference between usegalaxy.org and testgalaxyproject.org? I am a little confused. I am now trying to move my different files from usegalaxy.org to the other but I did not find any other option than to download all my files from the first and upload them all to the second, so it is taking a very very long time and I am not sure that this is what I need to do. I am not sure I am doing things as I should do.
Can somebody help me?
