Problem with Phylogenetic tree construction

Technical Support
1

Hello

I want to construct phylogenetic tree for bacterial sequence. I used a reference-based fragment insertion approach.

This is the command I ran

qiime fragment-insertion sepp --i-representative-sequences si_cs.qza --p-threads 40 --p-alignment-subset-size 1000 --p-placement-subset-size 5000 --o-tree Phylogeny[Rooted] --o-placements Placements

This was the error I got

p_error

Plugin error from fragment-insertion:

See above for debug info.

Could you please help me how to solve this error?

This might take a bit to troubleshoot, so please be patient with us! Could you please run the command,

locale

and share the result here?

Best,

Hi @Asha1,

This is an easy fix, then!

Please run

export LC_ALL="en_US.utf-8"
export LANG="en_US.utf-8"
locale

You should see everything set to en_US.utf-8.

If you want to solve the problem forever, on a mac you can add this line to your ~/.bash_profile and on a linux server your ~/.bashrc, which is kind of a master file which tells the system how to configure itself self.

Best,
Justine

What to do now Ma'am?

Can you please run the command with the --debug flag and post the results?

Hi @Asha1,

Based on your other post, is this ITS or 16s? The current fragment insertion doesn't support ITS.

Best,
Justine
