MySignalData here has multiple 1x1 structs like DIA,DIB,...DIZ,timestamp. Each DIA etc. has multiple 1x1 structs like pt1151,pt9999 etc which has a Data variable. I want to remove the last element in Data such that the size is 21707x1 and I want to apply this to all such ptxxxx in DIA,...DIZ.
How do I vectorize this process or I need to do in a for-loop? Even with a loop, it seems a daunting exercise. Any input is welcome.

Most likely you will need two loops and to use both of these:
It would be simpler with non-scalar structures, rather than putting meta-data into fieldnames.

To remove filed from structure check rmfield.
Example:
s.a = 1;
s.b = 2;
s.c = 3;
Remove field b.
field = 'b';
s = rmfield(s,field)
s = struct with fields:
a: 1
c: 3
