SOLiD raw data is usually more liberally returned then say Illumina data so you will notice more reads with dots etc. You could use an aligner that can handle the dots (such as BFAST; I am the author of BFAST). I suspect the vast majority of your reads don't have dots. As for primer sequence, programs like BFAST will align those as an insertion at the end of the read.

SAET does not only deleting the reads which do not pass the threshold, or trimming the bases which do not either, but it also makes some sort of consensus of reads, which is something you might not want to do if you want to know that what is there is what came out of the machine, as is.

I recommend q-trim from the cartwright lab, it is in python.
