Errors in test output

[roopavsm]

The following are the errors occurring frequently in the output using the image analysis tool:

• Subscripts are not read accurately. Eg: Cs
• The letters in the beginning and ending are missing. Eg: cetyl-C
• Words having hyphen symbols are not read completely(mostly in the end). Eg: hex-3-en, 3-Hydroxy-3-met
• Greek letters are truncated. Eg: -ketoacyl-A
• Numbers are not read completely. Eg: 1.2.1.3 (in the image) -> 1.2. (in the result)
  (4,1,3,29) -> (4,1,

Thanks!
~The hyphens are a problem on their own. Suggest you create a small number of images where this is a problem and open a new issue on "subscripts" and point to the examples, as it will need new code.
