Origin Ver. and Service Release (Select Help-->About Origin): OriginPro2017 SR1
Operating System: win10

Hi,

I´m new in Origin, so sorry for stupid question. I have a data from my experiment and I need to sum data in one row from selected columns. The problem is, that some of the data are like string (e.g."< 0.5"). I don´t need to add these values to the final sum (actually it is mistake), but what I need is to skip these data and sum only the "true" values from another columns in the "samle row".

Thanks for any advice.

One way to do this is to mask your data and then use statistics on rows to calculate the sum. When you mask data in your worksheet, the data will not be included the analysis.

You will first plot your data on a graph. With the graph activated select the Cluster Gadget.
Move the ROI box to select all data points you want to mask.
Select the mask tab in the Cluster Gadget dialog box. This will mask the data in the graph and in the worksheet.
Close the gadget dialog box and close the graph.

Now select your rows in the worksheet and select Statistics -> Statistics on Rows -> Select Sum in Quantities. Select ok.

Hi,

You also if you do not want to use the cluster gadget, you can use the script below to mask all data points that are <0.5.

get col(A) -e numpoints;

loop(jj,1,wks.nCols)
{
for(ii=1; ii< numpoints; ii++)
{
if(Col($(jj))[$(ii)] < 0.5)
Col($(jj))<$(ii)> = 1;
else
Col($(jj))<$(ii)> = 0;
}
};
