Please email xinranli@lbl.gov with your preferred account name. I'll create the account with a temporary password. After the first login, please change your password, and add your ssh key:

On your local computer:

$ ssh-keygen

Password is optional. Then

$ cat ~/.ssh/id_rsa.pub

Copy the output 'ssh-rsa xxxxxxx username@hostname'

Then ssh to your Tessy account

$ mkdir -p /home/user_name/.ssh && touch /home/user_name/.ssh/authorized_keys

$ vim /home/user_name/.ssh/authorized_keys

Paste the public key, save and close file.

Most users will need pytesdaq detprocess and jupyter to do analysis. Please follow the instructions below to install the packages:

1. Install miniconda

[xxx@tessy ~]$ mkdir -p ~/miniconda3

[xxx@tessy ~]$ wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh -O ~/miniconda3/miniconda.sh

[xxx@tessy ~]$ bash ~/miniconda3/miniconda.sh -b -u -p ~/miniconda3

[xxx@tessy ~]$ rm -rf ~/miniconda3/miniconda.sh

2. Configure conda virtual environment

[xxx@tessy ~]$ ~/miniconda3/bin/conda init bash

Exit and reconnect. Or [xxx@tessy ~]$ source ~/.bashrc. Now you should see the command line starting with (base)[xxx@tessy ~]$

The default conda environment base is python 3.11. We need python 3.10 for vaex (https://github.com/vaexio/vaex/issues/2368). So let's create a new environment:

(base)[xxx@tessy ~]$ conda deactivate

[xxx@tessy ~]$ conda create -n py3_10 python=3.10

[xxx@tessy ~]$ conda activate py3_10

You may add the first and third lines to the end of ~/.bashrc such that conda enters the py3_10 automatically next time you log in.

3. Install packages. Make sure you are in the correct conda environment. Conda suggests using conda install package_name first, and if the package can not be found, use pip install.

(py3_10)[xxx@tessy ~]$ conda install -c conda-forge vaex

(py3_10)[xxx@tessy ~]$ conda install jupyter

(py3_10)[xxx@tessy ~]$ pip install pytesdaq

(py3_10)[xxx@tessy ~]$ pip install detprocess
