Hi,Arek Kasprzyk.I had used biomart and confronted some difficulties, I couldn't find solution in google, and had no idea which Users Mail List to send to, So I write this email.First, I had delete report GUItab, and I want to make report now, how can I make report GUItab again? I had made a GUItab called reporte, but after selecting config, the following step "choose attribute" didn't show up. I find that the properties of new report GUItab is martform, while the raw GUItab is martreport, but I cann't modify the new properties to martreport.Second, I had finished all the job in my own computer, and scp biomart.registry.file, biomart.registry.key.file to serverce. The biomart is deployed in http://www.ABC.org:9000 and my database is in http://www.ABC.org:3306. If I want to get all configured in xml without raw xml file, How should I do? I had follow part 5.4 of document, adding a new RDBMS Source, when I fill Host:www.ABC.org, Port:3306, Username and Password as my database, and select Relational mart, there would be some databases available in the left panel, not marts as document, so I cann't find "Do you want to use the existing config?" I had try to fill as Host:www.ABC.org, Port:9000, but it doesn't work, I think I shold use another Username and Password, but what it is? In a word, how can I get config that I had done?Thank you for your help!Best wishes!&nb sp; Zhong Xiaoming
