Import and edit .asc data

D S

Posted 2 years ago

Hello! I'm a rookie and I would like to import .ASC file. It's a table with 2 columns separated by a space. I want to separate both (in x and y) and then link them via transpose command. How do I get from the raw data to two separated sets of data? So far my approach has been: asc = SemanticImport["ref 1.asc" , <\|1 -> Automatic\|>, "List", ExcludedLines -> Range[1, 56], Delimiters -> " "]; The output is: {"4000.000000 99.579746", "3999.000000 99.571567", "3998.000000 99.565144", "3997.000000 99.563823", "3996.000000 99.567302", "3995.000000 99.572190", "3994.000000 99.574877", "3993.000000 99.573919", "3992.000000 99.570546", "3991.000000 99.567511", "3990.000000 99.567216", "3989.000000 99.570202", "3988.000000 99.575037", "3987.000000 99.579679", "3986.000000 99.583246", "3985.000000 99.586611", ... and so on

Using the example provided (ignoring the `\` characters) importData = {"4000.000000 99.579746", "3999.000000 99.571567", "3998.000000 99.565144", "3997.000000 99.563823", "3996.000000 99.567302", "3995.000000 99.572190", "3994.000000 99.574877", "3993.000000 99.573919", "3992.000000 99.570546", "3991.000000 99.567511", "3990.000000 99.567216", "3989.000000 99.570202", "3988.000000 99.575037", "3987.000000 99.579679", "3986.000000 99.583246", "3985.000000 99.586611"}; data = importData // Map[StringSplit/*ToExpression]; ListLinePlot[data]

Using the example provided (ignoring the \ characters)

importData = {"4000.000000 99.579746", "3999.000000 99.571567", 
   "3998.000000 99.565144", "3997.000000 99.563823", 
   "3996.000000 99.567302", "3995.000000 99.572190", 
   "3994.000000 99.574877", "3993.000000 99.573919", 
   "3992.000000 99.570546", "3991.000000 99.567511", 
   "3990.000000 99.567216", "3989.000000 99.570202", 
   "3988.000000 99.575037", "3987.000000 99.579679", 
   "3986.000000 99.583246", "3985.000000 99.586611"};

data = importData // Map[StringSplit/*ToExpression];

ListLinePlot[data]

I have found a way (for the first line exemplary): ToExpression[StringSplit[asc[[1]]][[1]]] And then I can extract the data via a table.
