temp_wh.dat does not exist

[Wydneuro]

In my file path, temp_wh.dat exists, but when running phy2, show “temp_wh.dat does not exist”，I don't know why？

When I click on your link the picture is not opening. Could you post the contents of your params.py file? It chooses where to look for the temp_wh.dat based on the path given in that file.

I think I encounter the same issue, and I upload my screenshot here.

Unfortunately, I have other issues where phy2 does not allow me to create TraceView, the amplitude is blank & the waveformview looks weird. Not sure whether these associate with the temp_wh.dat does not exist.

Could you install with the environment.yaml instead. You need to download it then edit it to say python<3.12. That should fix the mime issue.

Hi @zm711 ,

Thanks for your reply, can I download it on the Anaconda directly because I don't have access to python?

What about the issue "tmp_wh.dat does not exist", the location "C:\Users\HP-lab\Desktop\SORTING" is not the location where my params.py files is (The D:\22-01-2024\SingleUnit is the location that I want). I wonder whether this may be the cause of this issue.

Thanks

@Moyu0014,

Yes you can do this through Anaconda (you actually have python through Anaconda :) ).

So first if you have git or github desktop access you can clone the repo. If you don't then you can download a zip of the files. Inside the files you'll see that there is a file called environment.yaml. You just open that and find the line where it says python and change that line to be python<3.12.

then you need to open your anaconda prompt and type

conda env create -f environment.yaml

The file might be .yml (depends on the tag you gave so if it gives a file error )

conda env create -f environment.yml

As far as the file location you could edit the params.py to point it to the correct location. Just open that file and you'll see the

dat_path=xxx

You would just need to edit that path.

Hi @zm711,

Thanks for your reply! I just ran the code and it displayed a conda value error below:

CondaValueError: prefix already exists: C:\Users\my name\anaconda3.

What shall I do next?

Best wishes,

First you have to run

conda remove --name phy2 --all

To remove the broken install of phy2. You have to be in base to do this so if you are in phy2 you would type

conda deactivate

first. If you're already in base then just do the one command I posted.

Hi @zm711 ,

I changed to another PC & this issue no longer happens, but I have another issue when I run Kilosort 3. Matlab was giving me the error Unrecognized field name "dmin", but I am pretty sure dmin exists Rez.ops. I am new to matlab, so can you let me know how to solve this in detail, please? Thanks very much!

Kind Regards,

That's a Kilosort question and not a Phy question. Unfortunately the Kilosort team is busy working on Kilosort4, so I'm not sure they will be able to answer. I don't have any helpful tips except try running a different dataset and see if this is a global problem for you or an individual problem. I have been able to get Kilosort3 to work for myself, so I can tell you it works. But just not sure.
