I use "Select" in "Filter and Sort" to sort my sam file in my local Galaxy.But I got "no peek " under "Matching pattern: ^@" ,while I got the same sam file under "NOT Matching pattern: ^@" .Actually,I can got the correct results in Galaxy main,I don't know what happened to my local Galaxy .I use 009088d5e76f as my local Galaxy.
