I think you have a non-printing character in your matrix. 
Min[2,3,4,5,x] reduces to Min[2,x]. But if the "x" was something so 
strange that Mathematica did not have a way of printing it, then I think 
we would see Min[2,].

If "data" is stored as a list of 17 row, each of which should contain 
248 numbers, then look for a row with Length[row] = 249.
