Hello everyone.!

I am new with Knime, and would like to learn an approach to my very first task wich is as follows:

I have an Excel file (Test Knime) where there are a lot of transactional movements for an inverse bidding, and need to capture the parameters in order to get the lowest bid (Colum: Amount) for each product (Column: Key).

After that, it is needed to make the same study but with grouping the amount column by ranges.

Any help will be very appreciated.

Thanks in advance

Hi, I am trying to store a metanode in node repository by following the metanode description shown in org.knime.workbench.repository(pasted below).

Could someone explain more detail about step 5 (Fill out the attributes) ?

I would also like to confirm if "runtime workspace" is /Users/username/knime-workplace or not.

Hi there. I've got the following situation:
I've extracted the name of a file from a string via the 'Column Filter' node, and I want to use this file name as a part of a command in a following step. The idea is, that I start a command line tool, and the filename shall be a part of this command. But as far as I know, I can not give this name to the 'Bash' node (which also has no Input port), and I don't find any way how to use the 'CmdwInput' node for this.

Will it be a good way to use a joiner or merger node to set up the command I want to have, and give this to the 'CmdwInput' node?

Thanks for your help.

JFYI, that there is, since some time back, an overarching Eclipse RCP / plug-in development community as well.
