I understand it right? You want to compute an multiple alignment of 37000 sequences at once?
There are no multiple alignment programs in the world that can compute a multiple alignment of 37000 sequences to my knowledge.
What you can try is to cluster the sequences according their pairwise sequence alignment and compute multiple alignments for similar sequences.
But you will need a fast algorithm like BLAST algorithm and this on to on is not implemented in R.
