Hi - you need to change your command - in the python -c you are trying to connect to port 5557 - but your guppy server is on port 5555 - so try this:
python -c 'from pyguppy_client_lib.pyclient import PyGuppyClient as PGC; \ c = PGC("ipc:///tmp/.guppy/5555", "dna_r9.4.1_450bps_fast.cfg"); \ c.connect(); print(c)'

Hi @jennieli421
Sorry about the slow response on this. I'm afraid I can't really help without a bit more information. How have you installed minKNOW? If you are running on Ubuntu and installed by adding the ONT repository and sudo apt-get install minion-nc
(or something similar), a systemd service file willl have been created, meaning that guppy_basecall_server
will automatically start. This can then be managed by a set of controls sudo systemctl <start|stop|restart|status> guppyd
. You can check this by using the status option in the terminal and seeing the output.
sudo systemctl status guppy
The problem with this is that guppy is run under a different user and group - one called minknow
. This means that you need to alter the permissions if you are to work with readfish - discussed here: #221 (comment)
This shouldn't be your issue here though. I saw in your issue on Squiggulator hasindu2008/slow5tools#92 that you chmod'd the bulk FAST5 file. This is a necessary - but can you try redownloading the file and trying again?
Cheers,

When I installed MInKNOW on Ubuntu 22, I followed this tutorial.
The commands I run:
sudo apt update
sudo apt install wget
wget -O- https://cdn.oxfordnanoportal.com/apt/ont-repo.pub | sudo apt-key add -
echo "deb http://cdn.oxfordnanoportal.com/apt focal-stable non-free" | sudo tee /etc/apt/sources.list.d/nanoporetech.sources.list
sudo apt update
sudo apt install ont-standalone-minknow-gpu-release
So I haven't use commands similar to sudo apt-get install minion-nc
. WHen I run this, I got an error:
The following packages have unmet dependencies:
minknow-nc : Depends: minion-nc (= 21.06.2-1~focal) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
Not quite sure how to fix that.
Additionally, by running sudo systemctl status guppy
I got "Unit guppy.service could not be found."
from readfish.
Apologies, for guppy that should be
sudo systemctl status guppyd
The minion-nc command I believe may be old , and officially I don't think that ONT support Ubuntu 22 (Jammy Jellyfish) yet!
I did have a similar issue recently following the tutorial - but I believe the fix was the chmod on the BULK fast5 file.
Can you try starting playback again and post the MinKNOW control server logs here (/var/log/minknow/<flowcell id>/control_server_log-0.txt
and /var/log/minknow/mk_manager_svc_log-0.txt
)?

I redo the steps as mentioned in the first post. still having "Run error". Here are the log files:

Another important question:
Will readfish be compatible with the new version of flow cell R10.4.1? We would like to test readfish (real-time enrichment) using the new kit and flow cell once they come in next week.
from readfish.
So looking at the control-server-log-0(1).txt, I can see
2023-06-16 10:08:22.746498 WARNING: hdf5_error (fast5)

ReadFish is indeed compatible with R10.4.1 - you will just have to change the base caller model in the TOML file.

The playback permission issue is resolved. In addition to chmod 777
, we also sudo usermod -a -G admin minknow
to give permission to the right group. After that playback is fixed.
The unblock-all
is working.
However, the targets
command gives error:
2023-06-16 13:27:29,636 ru.ru_gen Region 'select_chr_12_start' (control=False) has 2 contigs of which 0 are in the reference.

I run guppy in a separate terminal, then started playback in minknow, then run targets
command.
I couldn't tell if it was working from the histogram. The run report is attached.

Hey @jennieli421 - great news you have gotten it working! 🍾 This LOAD_CONFIG
is a problem a lot of people get caught out by, when running on a non ONT box, due to all the fun that comes with minknow
group permission errors. We're working on putting some notifications in the code for this, but I believe that if you have a look at this comment on another issue you should be alright! #221 (comment)
I'm surprised that sudo usermod -a -G admin minknow
hasn't fixed it though, so let me know if that link fixes it or not!
from readfish.
Still getting the LOAD_CONFIG error. This is what I've done:
sudo usermod -a -G minknow $USER
groups tilgnerlab
tilgnerlab : tilgnerlab adm cdrom sudo dip plugdev lpadmin lxd sambashare minknow
groups minknow
minknow : minknow tilgnerlab
sudo chmod 775 /tmp/.guppy/5555
ls -al /tmp/.guppy/
total 8
drwxr-xr-x 2 minknow minknow 4096 Jun 16 12:25 .
drwxrwxrwt 24 root root 4096 Jun 20 11:05 ..
srwxrwxr-x 1 minknow minknow 0 Jun 16 12:25 5555
from readfish.
So the umask for files in linux is User/Group/Other. So as a part of the minknow group, you should have read write and execute on the socket file, but either there or is something else going wrong here or you don't.
Can you try the yolo approach, just to see if it works and chmod 777 /tmp/.guppy/5555
?
You can test the connection using the snippet at the following comment, if you aren't already - #221 (comment)

Hi @jennieli421 - last effort then happy to arrange a zoom call! What is the host set to under caller_settings
in the TOML file that you are passing to readfish?
If it isn't 'ipc:///tmp/.guppy/' that might be the issue? Port should remain 5555
Also apologies but the chmod command above should be
sudo chmod 777 /tmp/.guppy/5555
Can you try that, just to see if it solves the issue?
Thanks,
Rory
from readfish.
Here is the TOML file:
[caller_settings]
config_name = "dna_r9.4.1_450bps_fast"
host = "ipc:///tmp/.guppy/5555"
port = 5555
[conditions]
reference = "/home/tilgnerlab/readuntil/hg38-ont.mmi"
[conditions.0]
name = "select_chr_1_10"
control = false
min_chunks = 0
max_chunks = 2
targets = '/home/tilgnerlab/readuntil/readfish_files/ReadFish_v7_gene_targets.collapsed.hg38.txt'
single_on = "stop_receiving"
multi_on = "stop_receiving"
single_off = "unblock"
multi_off = "unblock"
no_seq = "proceed"
no_map = "proceed"
Also changed permission:
ls -ltrh /tmp/.guppy
total 0
srwxrwxrwx 1 tilgnerlab tilgnerlab 0 Jun 16 12:25 5555
Still have the LOAD_CONFIG error.
from readfish.
So the host in the toml file should be just ipc:///tmp/.guppy/
and not ipc:///tmp/.guppy/5555
. can you try running after changing that?
from readfish.
That resolved the problem!
To summarize, to run readfish target
the key steps are:
sudo chmod 777 /tmp/.guppy/5555
in TOML
[caller_settings]
config_name = "dna_r9.4.1_450bps_fast"
host = "ipc:///tmp/.guppy/"
port = 5555
Connect to guppy in a separate terminal:
guppy_basecall_server --config dna_r9.4.1_450bps_fast.cfg -p 5555 -l /tmp/guppy -x 'cuda:0'
Start playback.
In a separate terminal:
readfish targets --device MN19362 \
--experiment-name "RU_test" \
--toml /home/tilgnerlab/readuntil/readfish_files/human_chr_selection.toml \
--log-file ru_test.log
from readfish.
Yes. You actually can also add your own User to the Minknow group and simply run
sudo chmod 774 /tmp/.guppy/5555
. This is slightly more secure - allowing any users in the minknow
group to use the 5555
socket file.
Connect to guppy in a separate terminal:
guppy_basecall_server --config dna_r9.4.1_450bps_fast.cfg -p 5555 -l /tmp/guppy -x 'cuda:0'
If you have a standard MinKNOW setup, guppy should be started automatically when you boot your computer.
But otherwise yes!
I'm going to close this issue for now.
