How to change column names in table?

1

I built a table with Merge, Paste and Cut, but now the bold header line is just 0, 1, 2 as the column names. How can I change the column names (or earlier, and how to keep them names)?

Thank you in advance.

Hi @viki
The bold header line: do you mean text in white font on blue background? This is ‘metadata’, hence names depend on datatype. If your file tabular, you’ll see 1, 2, 3. If you deal with other tabular formats, for example, BED, you’ll see other values. If you change the datatype, the header might change.
Kind regards,
Igor

I see, so as long as my dataformat is tabular, column names will always be 0, 1, 2 etc.?
And there is no chance to overwrite default metadata so I can have my custom column names instead?

Best,

Some tools can add info to metadata, so you might see 1.something 2.samethingElse in the output file, but when you upload the same file to Galaxy, most likely you’ll see 1, 2 etc.

You can add a header line to a tabular file using Concatenate.

Kind regards,
