Make some corrections about a relative complex matrix

I have received a relative complex matrix made with Tikz. I would like to do some modifications on a few points.

Here the source :

which produces the following rendering :

Modifications to apply :

1. I have marked in red the 2 sections to modify : I need the same size for the text $F_{0,O}$ $F_{30,30}$, $F_{0,30}$ and $F_{30,0}$. But on the upper left, $F_{0,0}$ is overlapped with the dots and is not seen. for this 7x7 block, I need 6 dots line besides to the right inside and 6 dots column below also inside this block. I would like to avoid the overlapping between $F_{0,0}$ and the line/columns of 6 dots.

2. for red marked area on bottom right, I would like to align vertically $F_{30,30}$ with the 10 dots horizontally placed : these 10 dots are too much shifted to the right, so there is a little space between the left side of this 11x11 block and the begin of the 10 dots line. If we could remove this space, then, I could have a good alignment for $F_{30,30}$.

3. and Finally, the blue marked area corresponds to an issue of overlapping also : I would like that the text "bias spectro" to be a little bit higher, above the red cross in order to avoid having an overlap between this text and the red cross.

All these modifications are minor but necessary and I have not enough Tikz skills to solve it by myself.

So any help would be fine.

• Hello. The code you provide is clearly coming from an automatic export from some external software. It's really redundant and it could be interesting to clean it a bit. All the dots are drawn in the end with lines starting with \draw [fill=black]. It's possible to delete some of them. For the rest, a close look at the code should be self explanatory if you want to drag some text. Maybe you could give a try. May 11, 2021 at 11:54

Your code is from a tool, so it's difficult to modify.

I did it completely new, hoping to meet your needs:
