发帖数: 2 | 1 I have more than 2,000 groups need to be aligned, that's why I can't use
public web interface (although they have many options but I can get all more
options using command line) but to write shell scripts to run my alignments in
batch. I can't find the options to set score for mismatch and match nucleotide
in several multiple sequence alignment programs such as ClustalW, T-coffee.
The default values (1.9 for match and 0 for mismatch in ClustalW) do not fit
my case.
Desperately need some experts | y***u
发帖数: 64 | 2 what kind of sequences are they? DNA or Protein? I guess they are protein
sequences, since you are using CLUSTALW / T-coffee?
I am not familiar with CLUSTALW, since I don't use it. But I do know several
other alignment programs that give better results than CLUSTALW. Or if you
really want to use CLUSTALW, I may be able to look at the program and help you
figure it out.
You can email me for more details.
Good luck!

do you mean sth like this?
clustalw input.aln -gapopen=8.0
what software are you using? PC DOS stand alone clustalw or GCG? Unix or
windows? I am no expert, but I think this not that difficult, if you have an
ansi c compiler, I am sure you can do this easily.
For example, all parameters(like listed partially below):
*********************
/*
multiple alignment parameters
*/
float dna_gap_open = 15.0, dna_gap_extend = 6.66;
float prot_gap_open = 10.0, prot_gap_extend = 0.2;
