<p>Hi Gunter,</p>
<p>Have you tried "Interpret empty value as" <b>zero</b> or <b>previous
value</b>?<br>

<pre wrap="">Dear all,
I've just encountered a problem that technically is no bug but as I
have spent about an hour in tracking it down I thought I'd better report
it to the developers:
My Tektronix scope is willing to save the acquired data in a CSV
formats. The first few lines are headers. Then there is data - and the
very last line of the file consists of only a newline with no characters
besides that.
kst knows how to skip headers and even knows how to extract information
from them. It also is real fast in reading the data. But the completely
empty line at the end of the file by default is interpreted as NaN.
Everything now looks fine. Curves are drawn, but if I try to
low-pass-filter them the result is a vector of the size 0:
The filter tried to fourier-transform a curve containing a NaN and the
result was all NaNs.
Don't kow if in the case that the filter generated zero data a test if
this was the cause would be a good idea or a mechanism that ignores a
totally empty line at the end of a file. But I at least wanted to report
that I found this.
Kind regards,
Gunter.
