Karol Brzezinski proposed the following answer:
Hi Kyle,

If you use ymport.text() function, you don't have to append bodies (it
is included in the function).

If you want to differentiate between clump properties, you can do it in two ways (at least):
1) put each clump in a separate file and load it with different keyword arguments passed to  ymport.text() function.
2) put all the clumps in one file, and load them at once. Next, iterate over bodies in the simulation and apply required properties.

Please see example of using the second approach below:

####### input file with clumps "clumps.txt"
0.068037 0.02416 0.0017637 0.0011423 1
0.068615 0.022601 0.0014278 0.00077244 1

##### Yade script
from yade import ymport

spheres = ymport.textClumps('clumps.txt')

currentClumpId = O.bodies[0].clumpId 
color = randomColor()
for b in O.bodies:
    if b.clumpId != currentClumpId:#change color each time clumpId changes
        currentClumpId = b.clumpId
        color = randomColor()
        
    if isinstance(b.shape,Sphere):#colorize spheres
        b.shape.color = color

###

Cheers,
Karol
