N2T COLOR CODE FOR THE NOSE AND THE NERVE RING (PRINTS OF THE HEAD)
[See the code according to Cell Name]
N.B. This code does not apply to the ventral nerve cord (VC) and dorsal nerve cord (DC) prints.
Based on the original MRC Code Sheets. Curated by Z. F. Altun & D. H. Hall. Wherever appropriate, the changes from the original code is noted.

Notes:
- Cell names correspond to those in Cell List in Wormatlas and Wormbase
- As a general rule, red codes refer to print set 1 and black codes refer to print set 2
- Abbreviations: BLK: black; R: red; G: green; BLU: blue, V: violet, BR: brown (applies to MRC code); NR: nerve ring
- Single purple dot: IL sockets; Double purple dots: CEP sockets; Triple purple dots: OL sockets ; Purple cross: A mphid sockets; Single green dot: IL sheaths; Double green dots: CEP sheaths; Triple green dots: OL sheaths; Green cross: Amphid sheaths (applies to-New Code by Z. Altun)
- There is no code for seam cells

*Z. Altun notes for N2T, low power, Print sets 1 and 2:
- On print #175 all posterior arcades are marked (A1-A6 [blue A with red numbering])
- On print #186 A3 disappears
- On print #203 a new A (posterior arcade) appears next to violet C. This A then becomes A4 on print # 282
- After print #180, A2 is marked as 1 (i.e. A1 is mostly unlabelled or labelled as violet A while A2 takes on the number 1 or the label A1)
- Print #564; blue A1is actually A2(traced from anterior and verified)
- The two dorsal hyp 3 somata may be fused (see print #335)
- A posteriorly directed dorsal left process from hyp 3 (posterior one) ends on print # 510 and is displaced by IlsoDL
- On print #227 three ventral branches of A4 join to make one (Violet A-Red 4-Violet A), and then branch again in print #237 (blue A4-blue A4 - blue A4 or violet A-A-A.) Middle one disappears in print #246
- On print #516, all arcade codes are modified to reflect correct labeling as A1-A6 (New Code)
- Landmarks: the beginning of anterior bulb is around print #580 and the beginning of isthmus is around print # 779
