Hello,
I am trying to write spikedector data into .gdf files in binary format,
but I cannot.
I am setting the 'binary' param of the spikedetector to True (I checked
it using nest.GetStatus) but files are written in ASCII.
Do I need some special python package?
I am using python 2.7.5 and NEST 2.18.
Thanks in advance.

Dear Jasper,
In NEST 3, this should be possible.
Stine or Håkon, could you provide some advice?
Best,
Hans Ekkehard

Dear all,
a colleague of mine (in CC) and myself are implementing a spatially structured network in NEST (using current NEST master). We are wondering how to generate a population of neurons that are distributed on a regular grid plus a random jitter. This means that we want to end up with a spatial distribution as can be seen in Figure 8 in the tutorial for creating spatially structured networks<https://nest-simulator.readthedocs.io/en/latest/tutorials/pynest_tutorial/p…>. Below that figure one finds a code snippet; however, we believe that this does not correspond to the distribution of Figure 8.
In the documentation of NEST 2.20.1 we did find a code snippet that produces a jittered grid:
import numpy as np
# grid with jitter
jit = 0.03
xs = np.arange(-0.5,.501,0.1)
poss = [[x,y] for y in xs for x in xs]
poss = [[p[0]+np.random.uniform(-jit,jit),p[1]+np.random.uniform(-jit,jit)] for p in poss]
layer_dict_ex = {"positions": poss,
"extent" : [1.1,1.1],
"elements" : "iaf_psc_alpha"}
As is apparent, this code does not make use of NEST internal random number generation but rather produces a list of positions that is then passed to a layer.
Thus our question is: is it possible to create a jittered grid natively in NEST master?
Best regards,
Jasper and Anno
