[maker-devel] Error: Unknown argument: "max_hsps_per_subject"

[Michael Campbell]

Hi Quanwei,

Different versions/implementations of blast do have parameters. Based on the usage you posted my guess is that the parameter you want is “-max_hsps”

Thanks,
Mike

Then use "makeblastdb" to build the database. And then run "blastp -db ... -max_hsps_per_subject 1" following the example in the protocol. But it returns me an error: Unknown argument: "max_hsps_per_subject".  Why this happens? Is it because I am using a different version of blastp?
