error overlaying label file onto template using sliceSeries #19

Open tulste opened 4 years ago

tulste commented 4 years ago

Trying to use sliceSeries as a way to view labels on a template and I'm getting the following error message:

Error in dim(slice) <- dims : dims [product 41004] do not match the length of object [0]

used the following code:

anatVol <- mincArray(mincGetVolume(“secondlevel_template0.mnc”)) component1Labels <- mincArray(mincGetVolume(“new-coloured-labels/wholebrain-cluster-component1.mnc”))

sliceSeries(nrow = 5, ncol=5, dimension = 2, begin = 15, end = 165) %>% anatomy(anatVol, low=0.5, high=12.5) %>% overlay(component1Labels) %>% legend(“t-statistics”) %>% draw()

I checked that these files are in fact the same dimensions using mincinfo and using Display in minc to visualize. Moreover, the object created in the R environment show that they indeed have the same dimensions.

Thanks!

Error is due to the defaults of overlay not handling the range of values well, overriding with low and high fixed it.
