EasySpin forum

I'm using easyspin version 6.0.0-dev.34
when I ran my older script with string
eprsave('myfile',B,data); which worked in older version but got error message in the latest version.

Error using eprsave
Unable to open data file xxxx.DTA

How do I do to fix this problem?
Thank for all tips.

It seems that eprsave is not able to write access to the file. Make sure it is in a folder where you have write access, and that it is not opened by any other application.
