I have a large data set where I've put trials into a cell array. So each cell contains 1 trial and within that cell trial{1,1} there is specific information about the trial. The first column in trial{1,1} is time.
How do you access the first column for each cell?
In the end, I want to change the first column to have time start from 0. So I plan on doing time = time-1

Guessing as to what the structure is, try this:
trial{1} = {(1:10).', rand(10,1), 'Information'};
FirstColumn = trial{1}{:,1}
SecondColumn = trial{1}{:,2}
ThirdElement = trial{1}{3}
producing (in this random run):
FirstColumn =
1
2
3
4
5
6
7
8
9
10
SecondColumn =
0.76396
0.8182
0.10022
0.17812
0.35963
0.056705
0.52189
0.33585
0.17567
0.20895
ThirdElement =
'Information'
