Multiple sequence alignment (MSA) of proteins using specific matrix

Question

[RT!37]

I am willing to do MSA for a set of proteins using a specific scoring matrix . There are tools like clustalW, Muscle where one can give a matrix of choice . However, problem is that they switch it later to some other class of matrices and MSA obtained is not the outcome of externally supplied matrices. Is there any tool where output MSA is product of only externally supplied matrices.

thanks
