ASCII format (ascii)¶
2D depiction of a single molecule as ASCII text
This format generates a 2D depiction of a molecule using only ASCII text suitable for a command-line console, or a text file. For example:
obabel -:c1ccccc1C(=O)Cl -oascii -xh 20

O
If the image appears elongated or squat, the aspect ratio should be changed
from its default value of 1.5 using the -xa <ratio>
option. To help
determine the correct value, use the -xs
option to display a square.
Note
This is a write-only format.
Write Options¶
-w <characters> | |
Image width in characters, default 79 | |
-h <characters> | |
Image height in characters, default is width/aspect | |
-a <ratio> | Aspect ratio of character height:width, default is 1.5 |
-s | Display a square - this is useful for correcting the aspect ratio |
-t | Write the output molecule index and the title |
-m | Include a margin around the depiction |
