I have a .file file with values from a mems accelerometer. I need to import the data into matlab, but i have trouble handling the format.
The first line of the file is this:
Fri Apr 5 11:51:00 2024 51{'y': -0.06464344482421874, 'x': -0.6272808349609375, 'z': -10.453084448242187}
Any help?

Ran in:
unzip file.zip
ls *.file
file.file
str = fileread('file.file')
str =
'Fri Apr 5 11:51:00 2024 51{'y': -0.06464344482421874, 'x': -0.6272808349609375, 'z': -10.453084448242187} Fri Apr 5 11:52:00 2024 52{'y': -0.07464344482421874, 'x': -0.7272808349609375, 'z': -10.553084448242187}'
C = regexp(str,'([^\r\n]+)\d{2}{''y'':(.+?), ''x'':(.+?), ''z'':(.+?)}','tokens');
C = vertcat(C{:})
C = 2x4 cell array
{'Fri Apr 5 11:51:00 2024 '} {' -0.06464344482421874'} {' -0.6272808349609375'} {' -10.453084448242187'} {'Fri Apr 5 11:52:00 2024 '} {' -0.07464344482421874'} {' -0.7272808349609375'} {' -10.553084448242187'}
t = strtrim(C(:,1))
t = 2x1 cell array
{'Fri Apr 5 11:51:00 2024'} {'Fri Apr 5 11:52:00 2024'}
yxz = str2double(C(:,2:end))
yxz = 2x3
-0.0646 -0.6273 -10.4531 -0.0746 -0.7273 -10.5531

Worked thank you! One last question, in some files i have a second sensor so the first line instead of
Fri Apr 5 11:51:00 2024 51{'y': -0.06464344482421874, 'x': -0.6272808349609375, 'z': -10.453084448242187}
is
Fri Apr 5 11:51:00 2024 51{'y': -0.06464344482421874, 'x': -0.6272808349609375, 'z': -10.453084448242187} {'a': 0.7251908396946565, 'b': -2.2290076335877864, 'c': -0.7786259541984732}
How can i modify the line
C = regexp(str,'([^\r\n]+)\d{2}{''y'':(.+?), ''x'':(.+?), ''z'':(.+?)}','tokens');
?
