echo tRNA helixes are defined as "helix1", "helix2", "helix3", "helix4"

define helixes helix1, helix2, helix3, helix4

echo "helixes" is for joint of helix1,helix2,helix3,helix4

echo tRNA loops are defined as "loop1", "loop2", "loop3", "loop4" and "loop5"

define loops loop1, loop2, loop3, loop4, loop5

echo "loops" is for joint of loop1,loop2,loop3,loop4,loop5

echo tRNA non-canonical pairs are defined as "knot1", "knot2", "knot3" and "knot4"

define knots knot1, knot2, knot3, knot4

echo "knots" is for joint of knot1, knot2, knot3 and knot4

define lend 673-676B

echo tRNA "non-coupled" 3'-end is defined as "lend"; 5'-end is included in one of helices (colored by purple) and is fully linked with complementary bases

define anticodon 635-637B

echo tRNA anticodon is defined as "anticodon"
