Error importing .qza files into R as a phyloseq object

[ekquaye]

Hi JBisanz,

I tried importing .qza files (feature table, metadata file, taxonomy file, and a tree file) as a phyloseq object using the qiime2R package (version ‘0.99.6’), but I keep getting an error in the form
"Error in FUN(X[[i]], ...) :
numbers of left and right parentheses in Newick string not equal".

However,

1. I am able to create the phyloseq object without the tree file using qiime2R (version ‘0.99.6’)
2. Also, I am able to create the phyloseq object (including the tree.qza file) using an older version of qiime2R ('0.99.34') on a less powerful PC of mine.

Could you please help me overcome this error?

Interesting, this wouldn't be coming from qiime2R per se, but rather from the read.tree function of the package ape. It looks like this ?bug? was fixed in ape so I would think installing the latest version should fix your issue.

Thank you for the response, jbisanz.
I use the latest version of ape (version 5.5), but, unfortunately, the error still persists.
