Convert 8 bit signed integer to unsigned and then convert to int32

Fixing dihedral angles beyond 180 degrees limit to create smooth curves

QUESTION

Convert 8 bit signed integer to unsigned and then convert to int32

Asked 2021-Nov-10 at 01:47

I have a signed 8-bit integer (int8_t) -- which can be any value from -5 to 5 -- and need to convert it to an unsigned 8-bit integer (uint8_t).

This uint8_t value then gets passed to another piece of hardware (which can only handle 32-bit types) and needs to be converted to a int32_t.

How can I do this?

Example code:

If you want to get the negative sign back using 32-bit operations, you could do something like this:

QUESTION

Fixing dihedral angles beyond 180 degrees limit to create smooth curves

Asked 2021-Jan-22 at 10:59

I have an output from a commercial program that contains the dihedral angles of a molecule in time. The problem comes from apparently a known quadrant issue when taking cosines, that your interval is -180 to 180, and I am not familiar with. If the dihedral would be bigger than 180, this commercial program (SHARC, for molecular dynamics simulations) understands that it is bigger than -180, creating jumps on the plots (you can see an example in the figure bellow). Is there a correct mathematical way to convert these plots to smooth curves, even if it means to go to dihedrals higher than 180? What I am trying is to create an python program to deal with each special case, when going from 180 to -180 or vice versa, how to deal with cases near 90 or 0 degrees, by using sines and cosines... But it is becoming extremely complex, with more than 12 nested if commands inside a for loop running through the X axis. If it was only one figure, I could do it by hand, but I will have dozens of similar plots. I attach an ascii file with the that for plotting this figure.

What I would like it to look like is this:

Thank you very much,

This is called phase unwrapping.

As your curves are smooth and slowly varying, every time you see a large negative (positive) jump, add (subtract) 360. This will restore the original curve. (For the jump threshold, 170 should be good, I guess).
