Hi
I've been a user of originpro 7.5 for a while and we're currently changing to originpro 8.0
I used to use a script which can be seen below which is found at the following link
http://www.originlab.com/forum/topic.asp?TOPIC_ID=3381
get col(B) -e npt; // npt is the number of rows
nn=2*npt;
set %H -er nn; // double the number of rows
dwell=col(A)[2]-col(A)[1]; // dwell time
start=col(A)[1]; // first time value (row 1)
stop=start+dwell*(nn-1)); // last time value (row nn)
col(A)=data(start,stop,dwell); // fill in time column (1st half will be the same as before)
tmp=data(1,nn); // create a temporary dataset with nn rows
tmp=0; // set all values to zero
copy -b 1 col(B) tmp -b 1 -e npt; // copy existing Y values to tmp
col(B)=tmp; // copy tmp to col(B) (1st half will be the same, 2nd half will be zeros)
del tmp; // delete tmp
Basically its used to zero pad my data for FFT
It works fine in originpro 7.5
but in originpro 8.0 rather than zeros I get column numbers.
can anyone tell me what to change in order for it to work in originpro 8.0
thanks

Hi, Andrew
The sixth line
stop=start+dwell*(nn-1)); // last time value (row nn)
should be:
stop=start+dwell*(nn-1); // last time value (row nn)
Thanks
