Hi Michael,
You can access the meta data in column with the get_user_info global function such as below:
Tree tr;
string strInfoName = "ColumnInfo";
if( get_user_info(myCol, strInfoName, tr) )
out_tree(tr);
So the information such as from TDMS import is stored with storage name of ColumnInfo.
From script, such as script window, you can view the tree and get values with code such as:
wks.col1.info.tree.=;
wks.col1.info.tree.ColumnInfo.ImportFile$=;
