Read ASCII

data=asciiread(filename, dimensions, type of data)

Discussion

• The NCL function asciiread is used to read in ascii data
• The format must be known, because the second argument is the dimensions of the file (/rows,cols/)
• Reading in files of mixed type (e.g. strings and floats) is not recommended. NCL will see only the type you specify in the call
• NCL strings are limited to 257 characters, so if you have strings longer than this, read them in as characters and then convert to string with the chartostring function.

Examples

1. Time series data
2. Gridded data
3. Multi-columnar data
4. Multi-columnar data separated by delimiters
5. Using cut
