Python volume from string

[papsphilip]

I am trying to use the setAllVoxelsFromString() command but its not working.

Can someone provide an example? what does the string need to look like?

i want to fill a vector volume with values i have from a fga file. First 9 values are for volume size and bounds. The rest is the values

 

import hou
node = hou.pwd()
geo = node.geometry()


file = node.parm('file').eval()

with open(file, 'r') as f:
    data = f.read().split(',')
    volumesize = (data[0],data[1],data[2])
    bboxmin = (data[3],data[4],data[5])
    bboxmax = (data[6],data[7],data[8])
    
    data = data[9:]
    datastr = ' '.join([str(elem) for elem in data])
    
volume = geo.prims()[0]
volume.setAllVoxelsFromString(datastr)
