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 __ __/__\_ _/__/ \__ _/_/ \__ | | | | | | | | | | | | | | |___ _ Cl \_\__ _/ \_ __ \_\_ __/ \__ __/ \__/ \__/ | | | | | | | | 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.
This is a write-only format.
|Image width in characters, default 79|
|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|
