You could remove the header line first with something like this:

fileID = fopen('p_s.txt');
dataFormat = '%f %s';
C_text = textscan(fileID,dataFormat,'HeaderLines',1,'Delimiter','\t');
t = cell2mat(C_text(1));

And then use regexp to get the numerical values from the second column

There is for sure a better solution to this, but If you just want something that works, you can just add a few extra delimiters

fileID = fopen('p_s.txt');
dataFormat = '%f (%f %s %s %f %s';
C_text = textscan(fileID,dataFormat,'HeaderLines',1,'TreatAsEmpty',{'d'},'Delimiter','\tdB,)');
t1 = cell2mat(C_text(1));
t2 = cell2mat(C_text(2));
t3 = cell2mat(C_text(5));
