Hi there, I have a very odd problem. I am trying to import a txt file that contains biological data. At first, the data is a string, but ultimately (as there are species names and branch lengths for a species tree), I want to manipulate the file such that the species names are strings and the branch lengths are numbers.

I am making good progress; it is rather obvious how to split the file etc. But now I noticed that the biologist has entered some special symbols as part of the species names, e.g. / but also ' and ". The symbol / can easily be mistaken for a division when I use ToExpression, so I will just delete it. I can also delete ' if needed.

But: I simply don't know how to delete the " symbol.

"StringReplace[string,"""->" "] does NOT work.

How can I replace the symbol " by blanks in a string?
