Fixes bug introduced in #1161.
Attempting to link to a symlink results in
DataSink
pushing symlinks to the nipype working directory out onto the filesystem at large. Can reproduce by connecting aRename
node to aDataSink
node.Test verifies the behavior of copying and linking from a symlink, fails prior to fix. Final patch passes optional
copyfiles
arguments to secondary calls. That seems like the least surprising behavior.
