Hi,
I'm not sure what you mean. If you split up a component map (containing Z-values) then just because you end up splitting it into multiple files, each masked differently, the Z values within each subpart will not change. Therefore the interpretation of these values does not change and you will not get time series info necessary for fslnets...
