STATA TIPS #2: LONG STRINGS
Medical researchers often work with genetic sequence data or magnetic resonance imaging (MRI). Medical data also frequently include long doctor notes specific for each patient. With Long Strings in Stata 13, now you can easily work with such data and include these variables in statistical analysis.
Long Strings in Stata 13 introduces a new Stata data type (strL pronounced sturl) which can be up to 2-billion characters long! strL allows researchers to import plain text data (such as genetic sequence or doctor notes) and binary large objects (saved as PDFs or JPEGs).
