Write me a ChimeraX script that loads a set of mrc files labeled volume001.mrc through volumeN.mrc , sets them all to be cornflowerblue with a reasonable common isosurface level, then rotates them all to a known orientation specified in the script, and then records a movie of: cycles through all the images, rotates it 90 degrees along an axis, cycles them again, then saves the video to movie.mp4 .
Here is a ChimeraX script that does what you described:
```
# Load the MRC files
for i in range(1, N+1):  # replace N with the actual number of files
    volume = "volume%03d.mrc" % i
    open(volume)

# Set the color and isosurface level
for m in models():
    m.color = "cornflowerblue"
    m.isosurface_level = 0.5  # adjust this value to your liking

# Rotate to the desired orientation
from chimera import Matrix
rotation_matrix = Matrix.rot_x(30) * Matrix.rot_y(45)  # adjust these angles to your liking
for m in models():
    m.transform = rotation_matrix

# Create a movie
from chimera.movie import Movie
movie = Movie("movie.mp4", 30)  # 30 fps, adjust to your liking

# Cycle through the images, rotate 90 degrees, cycle again
for i in range(2):
    for m in models():
        movie.add_frame()
        m.show = True
    for m in models():
        m.show = False
    rotate_x(90)  # rotate 90 degrees around X axis
    for m in models():
        movie.add_frame()
        m.show = True
    for m in models():
        m.show = False

# Save the movie
movie.save()
```
Here's how to use
Write me a ChimeraX script that loads a set of mrc files labeled volume001.mrc through volumeN.mrc , sets them all to be cornflowerblue with a reasonable common isosurface level, then rotates them all to a known orientation specified in the script, and then records a movie of: cycles through all the images, rotates it 90 degrees along an axis, cycles them again, then saves the video to movie.mp4 .

Here's a ChimeraX script that should do what you're asking for. This script assumes that the MRC files are in the same directory as the script and are named `volume001.mrc` through `volumeN.mrc`. You'll need to replace `N` with the actual number of files.

```python
#!/usr/bin/env chimerax

# Set the number of volumes and isosurface level
n_volumes = 10  # replace with the actual number of files
isosurface_level = 1.0  # adjust as needed

# Load the volumes and set their color and isosurface level
for i in range(1, n_volumes+1):
    volume_name = f"volume{i:03}.mrc"
    load_mrc(volume_name)
    set_volume_opacity(0.5)
    set_volume_color("cornflowerblue")
    set_isosurface(isosurface_level)

# Set the orientation of the volumes
set_orientation("slerp", [0, 0, 1], [1, 0, 0], [0, 1, 0], 1)

# Create a movie
