Hi,
my aim is to read a file in and than search it.
A short part of the file:

T,6,2,14,2
T,21,1,15,1
M,53,15,1,15
T,62,14,16,14
...
I want to separate it by the first letter of the rows.

Mathematica code I use:
A = Import["location/file.txt", "Table"]
tMat=Cases[A, {T, ___}]
mMat=Cases[A, {M, ___}]

The problem:
Import generates a format that I cannot handle properly:
List[List["T,6,2,14,2"],List["T,21,1,15,1"],List["M,
53,15,1,15"],List["T,62,14,16,14"]]

I tried ToExpression and StringToStream and others but it won't work.
Thank you in advance
