Questions concerning lampcolor and file links

Hi Everyone:
I’m learning Radiance through the book with two questions about Tutorial One.
1) I’m wondering how to quit lampcolor after finishing the calculation.
2) About creating the leaves, the terminal gives me the feedback below for all the xform. I do put leaf_1.rad and leaves_1.rad under the same directory. Is there a solution to solve it?
oconv: warning - (!xform -n 2b -ry 20 -mx -rz -100 -ry 20 -s .15 -t 0 .04 0 leaf_1.rad): empty file
xform: cannot find file "leaf_1.rad"
oconv: warning - (!xform -n 3a -ry 25 -rz -65 -ry 0 -s .14 -t 0 .06 0 leaf_1.rad): empty file

Thanks in advance.

You need to make sure that your RAYPATH environment variable has "." in it (probably first).
