[kepler-users] reading ascii as array

[[BE] Ufuk Utku Turuncoglu]

Hi,

Thank you for your help. I read ascii file successfully but now i need 
to calculate minimum and maximum of the each column. So, Sequence To 
Array actor generates array but when i try to use Array Minimum actor it 
gives the,

ptolemy.data.ArrayToken cannot be cast to pyolemy.data.ScalarToken

i also use Array Element to split the columns of array and it also fails 
but it gets only first element of the specified column. So, is there any 
other way to reach each column seperately an an array type? If not i 
will try to split the ascii file as to sperate files which has different 
columns.

Additionaly, i will also ask to Sequence To Array actor generates the 
ArrayType(String) type data but my data is in double type. Does it 
generate error or mis calculation when doing arithmetic operation.

Thanks again,
Best wishes

Ufuk
