比如 我现在的的events 为[1,2] 对应的时间窗为[ [0 , 4] , [-1 , 3] ]
虽然我的请求有点怪 但是贵校在 BaseParadigm类的_map_events_intervals方法中有这样的处理

def _map_events_intervals(self, dataset: BaseDataset):
        event_list = self.event_list
        intervals = self.intervals

        if event_list is None:
            # use all events in dataset
            event_list = list(dataset.events.keys())

        used_events = {ev: dataset.events[ev][0] for ev in event_list}

        if intervals is None:
            used_intervals = {ev: dataset.events[ev][1] for ev in event_list}
        elif len(intervals) == 1:
            used_intervals = {ev: intervals[0] for ev in event_list}
        else:
            if len(event_list) != len(intervals):
                raise ValueError(
                    "intervals should be the same number of events")
            used_intervals = {
                ev: interval for ev, interval in zip(event_list, intervals)
            }

        return used_events, used_intervals

when I try to use another dataset not in the /datasets/demo, I don't know how to change the dataset , in another way, I don't know what the dataset should become

经使用刺激界面stim_demo.py发现，使用python3.10的环境会出现如下错误：
ImportError: cannot import name 'MutableMapping' from 'collections'
在3.10环境下lib下的collections的__init__.py文件里添加如下语句即可解决：
from collections.abc import Mapping
from collections.abc import MutableMapping
此时若出现以下json解码错误：
TypeError: JSONDecoder.init() got an unexpected keyword argument 'encoding'
可同样在3.10环境下lib下的json的__init__.py文件里的load函数处将如下语句更改：
def loads(s, *, cls=None, object_hook=None, parse_float=None, parse_int=None, parse_constant=None, object_pairs_hook=None,**kw):
更改为：
def loads(s, *, cls=None, object_hook=None, parse_float=None, parse_int=None, parse_constant=None, object_pairs_hook=None, encoding='utf-8',**kw):
此时，再运行stim_demo.py 即可成功
希望可以帮助装好了环境又不想切换的小伙伴

老师您好，已将研究机构信息发送指定邮箱[email protected]，请问多久可以收到中文使用手册。十分期待您的宝贵分享，如果效果良好本团队会在论文中鸣谢。

Hello ,thank you for a great job!!！ I'm a newbie in this area, is there any cheap equipment to collect data set for BCI ?

epochs = mne.Epochs(
raw,
selected_events,
event_id={event_name: used_events[event_name]},
event_repeated="drop",
tmin=used_intervals[event_name][0],
tmax=used_intervals[event_name][1]
- 1.0 / raw.info["sfreq"],
picks=picks,
proj=False,
baseline=None,
preload=True,
)

为什么这里要对tmax - 1.0 / sfreq

Would you mind giving some demos about stimulation or something else?

On the previous PR (now merged), I noted that there were several flake8 related issue. For open-source library, I think it would be nice to integrate pre-commit hook to ensure the code-styles of the library are consistent (https://pre-commit.com/), especially if you are expecting external contributors.

您好，很感谢你们做出MetaBCI这么好用的开源平台，可是我在安装的过程中一直遇到下面问题，希望您可以帮忙解决一下，谢谢！！！

Say hi to author team.

this metabci project is a great job.

while i checked 'brainflow/amplifiers.py' , there is only Neuroscan, Neuracle, and Curry8. These equipment is fantasy good, while i am using openbci now. Is there any opportunity to get openbci-cython-daisy module to be added in. Or i will try develop on this.

作者你好，在给出的demos/FBTDCA.py中，intervals=[(0.14, 0.64+0.1)], 是不是意味着测试的时候，时间窗也变成0.6s了，得到的是信号长度为0.6s时的结果？

在domes/brainstim_demos/stim_demo.py的行3处
from matabci.brainstim.paradigm import SSVEP,P300,MI,paradigm
应该改为
from metabci.brainstim.paradigm import SSVEP,P300,MI,paradigm

Hi

wanna try running the demos, but unable to do it, does everyone has the same problem? Using python 3.7 at windows 11.

1. How can I use my own local SSVEP dataset to import this framework for experimentation?
2. How to specify the local download location for datasets provided by META BCI, such as BETA datasets, to avoid duplicate downloads of datasets？
