Problems with WrapTo180 map

Hello,

I have a 288(lon) x 192(lat) dataset The longitude is from 0 to 360 but I would like to wrap it so that it is -180 to 180 instead. However, when I use wrapTo180, I seem to get lines all across my map, data where it should not be. I really don't know what I'm doing wrong. Has anyone else had this problem?

I don't seem to get the same outcome when I create my own randomized dataset, so maybe it is just this specific one. In any case, I have attached it below.

Any help would be appreciated.

Thank you,

Melissa

Duplicated by later http://uk.mathworks.com/matlabcentral/answers/216485-problem-when-wrapping-longitude-dataset but I will close this one as the newer one has the data attached and this one does not.
