loading waves with white spaces.

Tue, 06/09/2015 - 09:37 am

Hello.
I'm facing problems while loading from Igor Binary files.
Within the IBW-files the wave-names are already specified (2D-Data) and are user-chosen.
The problem is that there can be white spaces within the waves from the IBW file. And this leads to incompatibility.

I load the Igor Binary File using


   LoadWave strFile

while strFile is the String File Name.
afterwards I check for the first loaded wave with


   strDataFolder = GetDataFolder(1)
   strWave	= strDataFolder + StringFromList(0, S_waveNames)

and then I duplicate the wave using


   Duplicate/O $(strWave) IBW
   KillWaves/Z $strWave

Now this worked fine for me, but as soon as it comes to spaces within the ibw-Wave-Names (S_waveNames) the code fails at the duplication step.
In command line I am able to add white spaces for waves like this: "root:NN NN" but in the Function above I can not use this syntax. Of Course. Because then I would get a String. ;-)

The manual says, that it should also work by directly giving the name of the wave (to avoid the name with spaces) but it doesn't...


LoadWave/N=IBW strFile
LoadWave/A=IBW strFile

Any thoughts? Are there maybe symbols like \" or sth. to use " in code.

Within a data folder path, any liberal names within the path must have single quotes. So if you have a path and wave name like
root:folder 1:name with spaces
it must be quoted like this:
root:'folder 1':'name with spaces'
To help you with this, we provide the function PossiblyQuoteName(). So in code that computes a path like yours, you can use

String wname = StringFromList(0, S_waveNames)

String strWave = strDataFolder+PossiblyQuoteName(wname)

Wave w = $strWave

... now you can do things with w ...
