== Introduction ==

As of 6/29/26, Retro-Blockbalster is an internal Irwin Lab web tool for submitting a compound in SMILES format and receiving retro/analoging reaction results.

The current backend runs on Cluster 2 using epyc.

== How to Login ==

=== Off Site ===

Start the portal SSH/SOCKS tunnel from your laptop:

<pre>
ssh -vNL localhost:2222:gimel:22 -D1080 bromero@portal3.ucsf.bkslab.org
</pre>

Leave this terminal open.

In a second terminal, log into gimel:

<pre>
ssh -p 2222 bromero@localhost
</pre>

Then log into epyc:

<pre>
ssh epyc
</pre>

Confirm location:

<pre>
hostname
</pre>

=== On Site ===

If on the UCSF/lab network, direct login may work:

<pre>
ssh -o HostKeyAlgorithms=+ssh-rsa bromero@gimel.compbio.ucsf.edu
ssh epyc
</pre>

== How to Open Website (MUST USE) With SwitchyOmega ==

Start the portal SSH/SOCKS tunnel:

<pre>
ssh -vNL localhost:2222:gimel:22 -D1080 bromero@portal3.ucsf.bkslab.org
</pre>

In Chrome, set SwitchyOmega to:

<pre>
Protocol: SOCKS5
Host: localhost
Port: 1080
</pre>

Then open:

<pre>
http://epyc:8001
</pre>

When finished, switch SwitchyOmega back to Direct.

== Where The Website Lives ==

Project directory on epyc:

<pre>
~/Initial-BenZinc26-website
</pre>

Important files:

<pre>
index.html
run_job.py
backend/server_old.py
.env
</pre>

== .env Setup ==

<pre>
SMTP_HOST=smtp.gmail.com
SMTP_PORT=587
SMTP_USER=...@...com
SMTP_PASSWORD=....(GOOGLE_APP_PASSWORD)
FROM_EMAIL=...@....com
</pre>

== How to Start Backend ==

On epyc:

<pre>
cd ~/Initial-BenZinc26-website
python3 backend/server_old.py
</pre>

The backend currently runs on:

<pre>
http://0.0.0.0:8001
</pre>

Test from epyc:

<pre>
curl http://127.0.0.1:8001
</pre>

== How to Keep Backend Running ==

Use screen:

<pre>
cd ~/Initial-BenZinc26-website
screen -S benzinc26
python3 backend/server_old.py
</pre>

Detach:

<pre>
Ctrl-A
D
</pre>

Reconnect:

<pre>
screen -r benzinc26
</pre>

List screens:

<pre>
screen -ls
</pre>

Stop backend:

<pre>
screen -r benzinc26
Ctrl-C
exit
</pre>

== Test Input ==

A test molecule that returns reaction rows:

<pre>
CN(C)C(=O)NC1=CC=CC=C1
</pre>

Test with curl from epyc:

<pre>
curl -X POST http://127.0.0.1:8001/hello-job \
-H "Content-Type: application/json" \
-d '{"user_input":"CN(C)C(=O)NC1=CC=CC=C1 urea_test","email":"your_email@gmail.com"}'
</pre>

== Environment ==

The backend needs a `.env` file in the project root.

Do not commit `.env` to GitHub.

Example:

<pre>
SMTP_HOST=smtp.gmail.com
SMTP_PORT=587
SMTP_USER=benzinc26@gmail.com
SMTP_PASSWORD=GOOGLE_APP_PASSWORD
FROM_EMAIL=benzinc26@gmail.com
BASE_URL=http://epyc:8001
</pre>

== RDKit Environment ==

The retro reaction script uses RDKit through:

<pre>
/nfs/exj/Fe/scripts/common_db/arthor-env/bin/python
</pre>

Test on epyc:

<pre>
/nfs/exj/Fe/scripts/common_db/arthor-env/bin/python -c "from rdkit import Chem; print('rdkit works')"
</pre>

RDKit works on epyc. RDKit may fail on gimel.

== Final Result ==

Finished job

[[File:FinalJobEx.png|thumb]]

== Troubleshooting ==

=== Site Cannot Be Reached ===

Check that:

* Backend is running on epyc.
* The SSH/SOCKS tunnel is running.
* SwitchyOmega is set to SOCKS5 localhost port 1080.
* The browser is using http://epyc:8001.

=== Port Already In Use ===

Check port 8001:

<pre>
ss -ltnp | grep 8001
</pre>

Only kill processes owned by you:

<pre>
kill PID_NUMBER
</pre>

=== Email Not Sending ===

Check that:

* `.env` exists.
* Gmail app password is correct.
* SMTP_USER and FROM_EMAIL are the same account.
* The app password belongs to that same account.

== Notes ==

For office-wide use without SSH/SOCKS tunnels, Retro-Blockblaster will eventually be placed behind an internal hostname or proxy.
