There is actually two different webservices :
blastprodom: a blast (blastn or blastp) on ProDom database: enter a sequence (nucleotides or proteins, raw or fasta format) and it returns a blast output with the name of the families corresponding to the hits found and a URL to get the image visualising the blasted domains on the protein.We have a perl script available here to run this webservice from your computer. Please install SOAP Lite before .
blastpgpProDom: performs a recursive psi-blast (default = 10 iterations) from a query, a bank(fasta formatted sequences) and an alignment. The output of the webservice fetchdom_align is made to be the entry of this webservice. More otpions will be available soon.
