Hello,
You will need a working sequenceserver installation, i.e., with BLAST+ downloaded and database directory configured (all the things sequenceserver asks/automates for you during setup). The server should be running, for example, at
http://localhost:4567 (the default).
To visualise BLAST's XML output, run:
sequenceserver --import /path/to/xml/file
This will give you a job id, like:
0210b076-cddd-4d88-bc6c-057d7d5e07df
Copy the job id and access the results in browser at:
You will need to repeat the sequenceserver --import command for the different XML files
