G'day,Here's another example of the issue Tomas is talking about (from the MZmine software).
The artefacts appear when the sampling resolution along the m/z axis is high (attachment 1).
They're not present at lower resolutions (attachment 2). Floating point precision could well be the issue. Regards, Chris. On 22/05/12 08:11, Tomas Pluskal wrote:
Hi Tom, Thank you for the tip.I would like to try that, but what class should I use instead of the Linear2DSet? There seems to be only Gridded2DDoubleSet, but no equivalent for the linear set.By the way, please check the other batch of screenshots I sent: http://www.unidata.ucar.edu/mailing_lists/archives/visad/2012/msg00057.html There the same issue appears although the spacing between the data points is not so close (around 1).Tomas On May 21, 2012, at 10:41 PM, Tom Rink wrote:Hi Tomas, With the Linear2DSet you've defined, the points are pretty close, maybetoo close for single precision. You could try the double-precision versionof the Set classes.
