Hi everyone, 

I hope you all are safe and healthy.

I run a triaxial code for the following input data:

print ('============ DEFINING VARIABLES ============')
nRead=readParamsFromTable(
 num_spheres=20000,
 compFricDegree = 10,
 key='_triax_',
 unknownOk=True
)
from yade.params import table
num_spheres=table.num_spheres
key=table.key
targetPorosity = 0.4
compFricDegree = table.compFricDegree
finalFricDegree = 29
damp=0.2
thick=0.01
stabilityThreshold=0.01
r_min=0.1*1e-3  # m
d_min=2*r_min  # m
r_max=0.3*1e-3  # m
d_max=2*r_max  # m
r_avr=(r_min+r_max)/2   # m
d_avr=2*r_avr  # m
r_fuz=(r_max/r_avr)-1  # m
young=10e8   # Kn = 2 (E r1 E r2 / E r1 + E r2) >>> E = Kn/r_avr
Kn=young*(d_avr)   
Kt=Kn   
poisson=Kt/Kn   # Kt/Kn
Ls=0.02   # m
mn,mx=Vector3(0,0,0),Vector3(Ls,Ls,Ls)
volume = (mx[0]-mn[0])*(mx[1]-mn[1])*(mx[2]-mn[2])
strainRate=-0.5     # %/sec  
target_strain=0.25 
sigmaIso=-5e5        # Pa    
particleDensity=2000    #kg/m3

at the end of the computation, I want to save data on a text file with the following command:
plot.saveDataTxt('Macro_results')

knowing that I have defined the history function as follows:
from yade import plot
def history():
    plot.addData(
		e11 = -triax.strain[0],
		e22 = -triax.strain[1],
		e33 = -triax.strain[2],
		ev = -triax.strain[0]-triax.strain[1]-triax.strain[2],
		s11 = -triax.stress(triax.wall_right_id)[0],
		s22 = -triax.stress(triax.wall_top_id)[1],
		s33 = -triax.stress(triax.wall_front_id)[2],
		i = O.iter,
        t = O.time,     # virtual (yade) time --- time of simulation
        fab = utils.fabricTensor()[0])

The code runs with no problem until the end of the code, for line:
plot.saveDataTxt('Macro_results') 

And I get this error:
============ RECORD AND PLOT DATA ============
Traceback (most recent call last):
  File "/home/ehsan/yade/install/bin/yade-2019-08-08.git-775ae74", line 336, in runScript

    for i in range(len(data[vars[0]])):
IndexError: list index out of range
[[ ^L clears screen, ^U kills line. F12 controller, F11 3D view (press "h" in 3D view for help), F10 both, F9 generator, F8 plot. ]]


I want to know if should I use hd5 format file instead of txt file?

Thank you all.
