I have a large list of 40,000 file names = f1, each file name corresponds to 
a 360 x 19 matrix of real numbers,I need to run the calculation on each file 
and save the answer in a list of results. The method below works but is slow, 
is there a better way? Thank you. John R Moran PhD, MD.

    StandardDeviation, {Table[.01*
              Column[Partition[Drop[Import[f1[[j]], "List"], 1], 19], i]] // 
          N, {i, 2, 11}]}], {j, 1, Length[f1]}]
