How do I remove rows based on whether or not a substring in one column matches with a number in a second column according to a pre-defined criteria?
The criteria;
80ms,140ms & 1
100ms,250ms & 2
250ms,600ms & 3
600ms,900ms & 4
An example of the data below. I want to delete the rows below where 250ms,600ms is in the first column and the number in the second column is a number other than 3, and delete rows where 100ms,250ms is in the first column and a number other than 2 is in the second column.
'CG_11_21_250ms,600ms_CPR' 1
'CG_11_21_250ms,600ms_CPR' 2
'CG_11_21_250ms,600ms_CPR' 3
'CG_11_21_250ms,600ms_CPR' 4
'CG_12_22_100ms,250ms_FCL' 1
'CG_12_22_100ms,250ms_FCL' 2
'CG_12_22_100ms,250ms_FCL' 3
'CG_12_22_100ms,250ms_FCL' 4

Try the following:
T(contains(string(T{:,1}),'80ms,140ms') & T{:,2} ~= 1,:) = [];
T(contains(string(T{:,1}),'100ms,250ms') & T{:,2} ~= 2,:) = [];
T(contains(string(T{:,1}),'250ms,600ms') & T{:,2} ~= 3,:) = [];
T(contains(string(T{:,1}),'600ms,900ms') & T{:,2} ~= 4,:) = [];
