actually, I imported data via the method from this post Mafft 'returned non-zero exit status 1' ERROR - #5 by Purrsia_Felidae
namely, I construct unrooted tree in qiime1 with code
"pick_de_novo_otus.py -i split_library_output/seqs.fna -o otus",
then I imported the unrooted-tree in qiime2
import unrooted tree (phylogenetic tree)
qiime tools import \
--input-path unrooted-tree.tre \
--output-path unrooted-tree.qza \
--type 'Phylogeny[Unrooted]'
unrooted to rooted
qiime phylogeny midpoint-root \
--i-tree unrooted-tree.qza \
--o-rooted-tree rooted-tree.qza
but I when I tried to generate core metrics files, it reports like this
actually, when I work on qiime1, my computer run out of battery once. Is that the reason for this error? otherwise, I have no idea what is going on....and what to do next...do you have any idea about that? Thank you in advance!
sincerely,
