Error while running phylogenetic tree

Hi, I am new to Qiime2. I am following the Parkinson Mouse tutorial posted on the official QIIME2 website. However, when I try to generate the phylogenetic tree, it turned out to the error below.

I am using 2020.8 version of qiime, and it is installed in the docker on MacBook. I enter the code in the terminal.

Hope anyone to help me! Thank you so much!!!

Hi @adawangpc!

The sepp exit code 137 indicates that you do not have enough memory (RAM) available to compute this step. One option is to download the pre-computed tree from the PD Mice tutorial, that way you can carry on. Otherwise, you will need to find a way to access additional memory, which might involve using another computer.
