Working on subsection of EMG data

Hi all,

I'm new to Matlab, so sorry for this rudimentary question.

I have collected surface EMG data over a 140 minute time period. This resulted in a time variable and my EMG data in volts. For the data collection a sampling frequency of 1925.92 was used. I now need to calculate the mean root square of different subjections of the data. Since, the markers time were not recorded during data collection, I need to determine the start and endpoint of the subsections by hand.

I would like to know the best way to split my data into subsections in my data.

Any ideas are welcome. Thanks.

The simplest way (but can be cumbersome) is to plot the data and manually mark the starting and ending point of each section of data.

For automatic segmentation, it is depending on your data and there is no universal approach.
