I have a fasta genome file that contain 4000 genomic sequences (~ 30Mb size) in it. I would like to align this 4000 sequence to a reference genome. I was trying to use SINA (reference base multiple sequence alignment) in galaxy ( however I have got memory error. Is there any online sources that I perhaps can use for this purpose?

If you only need to align the sequences to a reference, I'd suggest blastn

You may also be able to use mummer:

If you have sequencing reads, you can use bowtie2.

Hi, try CSAR web. Just upload a reference and you 4000 genomic sequences and you will get an mummer alignment, a fast scaffold and a dot plot. But i really recommend that you perform this type of analyses locally in order to get more control of your work.
