ISIS-II Disk from Greaseweazel. No sectors

[WLong]

Hello to the Group!
I was able to get a flux level file (Greaseweazel) from an old (50+ year) 8" floppy used in an Intel MDS, hence ISIS-II file format. Inputting the flux file into HxC (raw image), I was able to generate a img file that shows the contents very well, but with one issue. No sectors. The img file appears to have no organization whatsoever. The original media had 77 tracks, 26 sectors per track, 128 bytes per sector and is double sided.

How can use HxC to write an image file in a format matching the original media?

Thanks
Bill
