Can you help me in sorting sequences alphabetically?

[joeytogo]

Hi,
Can you tell me how I could sort lists of sequences alphabetically? My files look like the list below. I want to sort by the .S--- suffix on the accessions. Can I do this in Textpad?
Thanks, Joey

There is a lot of missing information in your post, to help you properly. Is the data in a file? Is this a Windows command prompt output? Below is what I thought you meant. I sorted by "S" following the dot "." on the the > prompt line and also assumed that the long uppercase alphanumeric code follows the line above beginning with the >.

.SM143 is on top because of the ANSI/ASCII character order, then it's followed by .Saga

Thanks,
Yes, this is what I wanted to do. How did you do this?
Find what and replace with what?

I changed every pair into a single line by identifying, the uniqueness of the [.] and the [\n>] and replaced it with \t tab. This created 3 columns, which I sorted by the 2nd column. Then I reversed the process.
