How can I provide extra parameters to BWA using the "--bwa-params" option? #168

Hi,

I'd like to give extra parameters to BWA, but I can't know how to do it correctly.

Take the "-a" option as an example.

I tried the arguments below, but nothing worked. How can I give extra parameters to BWA?

--bwa-params -a --bwa-params '-a' --bwa-params "-a" --bwa-params a --bwa-params 'a' --bwa-params "a"

Also, error messages likely say that I have to use "--bwa-parameters", not "--bwa-params". What is the correct option to give extra parameters?

Thanks.

Hi,

Sorry I guess the documentation must be incorrect. I'm afk ATM so can't check properly, but maybe try

--bwa-parameters "'-a'"

You could also turn on debug so you know the right call is being made.

Thank you for your quick reply.

I've tested further.

The correct name of the option is "--bwa-parameters", not "--bwa-params".

This option seems to be available in "coverm make", but not in "coverm genome". I was confused because this option is listed on the usage page of "coverm genome". (https://wwood.github.io/CoverM/coverm-genome.html)

For "coverm make", "--bwa-parameters -a" seems to work.

Thanks.

Thanks for this @ilnamkang - it is fixed for the next version i.e. make accepts --bwa-params and --bwa-parameters, either is fine. Closing now.
