For multi file import, is there an option to load just a limited number of rows?
#lines To Read
#last line
No. Good wish list item though.
I submitted a wish:
@hogi asked about MFI. JMP has another way to open .CSV files via File->Open which has several subsetting options if you know where to look; the subset section is not open when the dialog first shows up.
Subset options - open the Subset outline node to see them.
