Hi
I have these operators set up: Read Excel>ReplaceMissing Values>Select Attributes
In Select Attributes I can see the menu of attrbutes and I am able to select from these and move these to the right,then click Apply
After clicking Run and switching to the results button a list of examples is shown but with no attributes selected at all
This problem happens regardless of whether I select all, subset or single attribute option
Any ideas why so?

    Hi,

    can you please post your process setup and a detailed description of your data (number of attribtes/examples, attribute names, attribute types)?

    Best regards,
    Marius

    Correction to my first post: The problem only exists with the sub-set option, not the single or all attributes option

    The data set: 29 examples, about 11 attributes, of which about 10 have been de-selected when imported. Almost all polynomial attributes

    Re "process set up" do you mean something other than the set of operayors that I have selected and used? Please excuse if this is a dumb question

    Further update, under the Subset option it will output two selected attributes that are integers, rather than polynomial.

    Problem seems to have been the "|" character in the field names. When it was removed all affected fields were now outputed as expected
    thanks, nevertheless

    Aah, that's probably because internally Select Attributes uses a regular expression. Next time, try escaping the bars with a backslash, i.e. instead of
    my|attribute
    write
    my\|attribute

    Best regards,
