William, it would help to see the bitmap or converted path to see if what I'm suggesting will work, but it was scrubbed. Here's what I would suggest.

Make sure that your converted bitmap is indeed a single path. You will get feedback about this in the taskbar when you select the object. If it says '1 group' or "two paths" or anything else selected, you must ungroup, etc, until you have a single path. A single path can of course have many many separated shapes in it with space in between them

Then, in the path menu, choose 'ungroup'. You should then see your shapes separated into a series of selection boxes all selected at once. Click away with the selector, then select individual circles. If you have overlapping circles, they will become a single object in a single path.

Hope this helps.

Dear all,

I have a bitmap with many circles inside it, and I would like to manipulate
each circle individually. I have already converted the bitmap to svg by
using Trace Bitmap inside inkscape, but I dont know how to "ungroup"  the
vectorized figure and manipulate the circles individually.

I would like to know if I can do that in inkscape and how. I am attaching an
example bitmap.

Thanks in advance.
