%>% not working with multiplicate or divide

[dorianps]

works with + or -
temp = ConAvgDiff.t1[[k]] %>% iMath('Normalize') %>% - brainmask

doesn't work with * and /
temp = ConAvgDiff.t1[[k]] %>% iMath('Normalize') %>% * brainmask
Error: unexpected '*' in "temp = ConAvgDiff.t1[[k]] %>% iMath('Normalize') %>% *"

[dorianps]

Never mind,
Subtraction/addition needs %>% before.
Division/multiplication works without %>%.

A bit confusing but at least works.

I'm not sure what you mean, but concatenating multiple atomic arithmetic
operators works just like in normal math:

r16 <- antsImageRead(getANTsRData('r16'))
mysum <- r16 + r16 + r16
mydiv <- r16 / r16 / r16
works as expected, with no need for special piping ("%>%").

I would use parentheses to make sure you're getting what you think you're
getting.
