Cannot import biom file in R about american-gut

[wasade]

These BIOM tables conform to BIOM Format 2.1 spec. It looks like there is a
discussion on the phyloseq tracker about updated support, see here:

joey711/phyloseq#443

I am new to biome file and try to download the biom here for testing. I
have click and save the raw file into my hardisk and tried to open it in R
using phyloseq and biom package but it returns :

"Error in fromJSON(content, handler, default.size, depth, allowComments, :
invalid JSON input"

I have copied and paste an example url (
https://github.com/biocore/American-Gut/blob/master/data/HMP/HMPv35_100nt.biom)
to some jason validator on web but it return a error.

Would you instruct on some materials that I can start with working biom
files from here? Thank you so much!

Regards,
Carol

As suggested in that thread, the best alternative at the moment would be
to convert the tables to JSON-formatted files.

Thank you very much! It seems works!

However, I've tried to convert the biom file downloaded to the txt format and it shows the following:

biom convert -i HMPv35_100ntj.biom -o HMPv35_100nt_tab.txt --table-type "otu table"
Traceback (most recent call last):

raise CommandError(convert_error_msg)
pyqi.core.exception.CommandError: Input does not look like a classic table. Did you forget to specify that a classic table file should be created from a BIOM table file?

It seems that the BIOM table file is not a classic one, how can I solve this? Thanks a lot!

Are you using biom v 1.3.1 for the conversion? If so, then you will not be able to convert a biom 2.x file. For instance, I was able to run the following just now:

$ biom convert --version
Version: biom convert 2.1.3-dev
$ biom convert -i AG.biom -o AG.biom1x --to-json --table-type='OTU table'

I'd be happy to host 1.x formatted tables on ftp.microbio.me but not within the Github repository as it is already hosting more data than it really ought to be.

@arcys, is this still an issue or can this be closed?

It is done, thx!
