Assertion error starting Phy2 for KS3 data

[HiroyukiKato7]

I'm not sure if this is related to #329, but I get an assertion error starting Phy2 for KS3 data. The same recording data sorted with KS2 has no problem. In case of #329, it seems that Phy2 at least opened, but in my case the Phy2 window does not even open. The error message is as follows:

←[31m17:08:41.799 [E] init:62 An error has occurred (AssertionError): Traceback (most recent call last): File "(path)\anaconda3\envs\phy2\lib\runpy.py", line 193, in _run_module_as_main "main", mod_spec) File "(path)\anaconda3\envs\phy2\lib\runpy.py", line 85, in run_code exec(code, run_globals) File "(path)\anaconda3\envs\phy2\Scripts\phy.exe_main.py", line 9, in sys.exit(phycli()) File "(path)\anaconda3\envs\phy2\lib\site-packages\click\core.py", line 764, in call return self.main(*args, **kwargs) File "(path)\anaconda3\envs\phy2\lib\site-packages\click\core.py", line 717, in main rv = self.invoke(ctx) File "(path)\anaconda3\envs\phy2\lib\site-packages\click\core.py", line 1137, in invoke return process_result(sub_ctx.command.invoke(sub_ctx)) File "(path)\anaconda3\envs\phy2\lib\site-packages\click\core.py", line 956, in invoke return ctx.invoke(self.callback, **ctx.params) File "(path)\anaconda3\envs\phy2\lib\site-packages\click\core.py", line 555, in invoke return callback(*args, **kwargs) File "(path)\anaconda3\envs\phy2\lib\site-packages\click\decorators.py", line 17, in new_func return f(get_current_context(), *args, **kwargs) File "(path)\anaconda3\envs\phy2\lib\site-packages\phy\apps_init.py", line 136, in cli_template_gui template_gui(params_path, **kwargs) File "(path)\anaconda3\envs\phy2\lib\site-packages\phy\apps\template\gui.py", line 187, in template_gui controller = TemplateController(**get_template_params(params_path), **kwargs) File "(path)\anaconda3\envs\phy2\lib\site-packages\phy\apps\base.py", line 676, in init self.model = self._create_model(dir_path=dir_path, **kwargs) if model is None else model File "(path)\anaconda3\envs\phy2\lib\site-packages\phy\apps\template\gui.py", line 84, in _create_model return TemplateModel(dir_path=dir_path, **kwargs) File "(path)\anaconda3\envs\phy2\lib\site-packages\phylib\io\model.py", line 276, in init self._load_data() File "(path)\anaconda3\envs\phy2\lib\site-packages\phylib\io\model.py", line 312, in _load_data assert self.channel_positions.shape == (nc, 2) AssertionError ←[0m

I would appreciate it if I could get help in resolving this issue.

Thanks

It seems that this happens when I exclude some channels for sorting. I can open Phy when I use the whole 64 channels. (This is from Cambridge 64-ch linear probe recording)

hi, similar problem here using phy2 to load data produced by kilosort3 (updated on sept 03, 2021). I didn't have the problem before.
