Origin Ver.9.1 and Service Release 1(Select Help-->About Origin):
Operating System: Win 7

Hello everybody,

I ran into the follwing somewhat strage result using wxt.
As a dummy code:

// create a worksheet with 1 to 1000 in col(a):
newbook Book1;
dataset aaa = {1:1:1000};
col(a) = aaa;

// Extract 1 line into new worksheet, e.g. the line with 123
// USE WXT:
wxt test:="col(a) = 123" ow:= Book2;

Now, the export works fine, but what strikes me is, that the new worksheet also contains 1000 rows of which 999 are empty.

Can this be avoided somehow using wxt?

In my scripts I am using wxt a lot to extract data from larger lists. I would like to keep the results worksheets small to avoid unnessary memory requirements for the huge "almost empty" worksheets.

Thanks for your help

Hi,

You can workaround it by using script below:


wxt test:="col(a)<10" ow:=Book2 num:=number; // Output passed row number
wks.nrows=number; // Set destination row number as passed number


The basic idea is to output number of passed rows and then set destination row number as the number of passed rows.

Hope this can be some help!

Regards!

Sean
