how to trim solid reads length?

[lei]

are there any tools available to trim solid reads length? for example, I want to extract first 30bp.
Thanks!

No tools that I know of. Both Emboss and Galaxy do not seem to have a way (although there are so many programs in both that it is hard to tell.) Trimming is trivial to do in perl or another language. If you are a "layer 3" bioinformatics person (see http://www.homolog.us/blogs/?p=85) then it will take less time to write the program than to respond back to this message. :-)

OK, I wrote one, but not so fast, that's why I ask here to check whether there is some tool to do it already.

I've managed to do it by double-encoding, passing through the fastx-toolkit, then reversing the double-encoding.

Are there any new ways to do this?

I don't understand. "trim" = cut ? zurechtstutzen
Nor do I know/understand Emboss,Galaxy,layer 3,
double-encoding,fastx.
I just feel, there must be something wrong with bioinformatics,
if cutting the length of a sequence gets a thread here.

Let's reiterate what westerman said:

Or, for that matter, reading through all the posts in this thread, then asking if anyone has thought up their new favourite way to trim reads to a particular length.

Lovely
