Dear all, At your recent AATRN talk, Dmitriy, you mention how the standard algorithm outputs a bounding chain; https://youtu.be/DEl6hCcGwag (11:40). Is there a routine in Dionysus for outputting the c

Hello Dmitriy, Has there been any update to binding persistence vineyards in python? I am hoping to use persistence vineyards for a few research applications relating to brain network dynamics, and wa

Hi Dmitriy, I would like to look at the vineyard of a time varying point cloud obtained from a distance matrix but I am unsure about the correct input data format and whether the pl-vineyard function

Hi Dmitriy, I was wondering if it possible to save the d.fill_rips and the d.homology_persistence objects and reload them later on so as not to recompute them? I was trying to pickle them but was runn

Hi, Dmitriy! I'm so sorry to ask this, but I'm a beginner in programming and I don't have enough experience in installing things. However I strongly intend to do some persistently homological stuff wi

Hi Dimitry, I'm using Dionysus 2 in python and I'm trying to find what the quickest way is to convert a persistence diagram into a pandas DataFrame. My current code looks like this: import numpy as np

Hi I'm trying to implement and integrate this work: https://epubs.siam.org/doi/epdf/10.1137/19M1272226 found in this repository: https://github.com/GWWEI/EnrichedBarcode/blob/master/enriched_ph/Enrich

i use d.zigzag_homology_persistence to compute zigzag persistence,and the input completeGVRips is 32644 Simplices and the related in and out time and the G_dgms is #Dimension: 0 Dimension: 1 #dgm Diag

Hello, This may be a somewhat basic question but I'm a bit stumped. How would I go about using Dionysus2 to generate a persistence diagram from a point cloud stored in numpy array? I tried the followi

Hi Dimitriy, I have been used Dionysus to compute the persistence diagram for a long time. But recently I encounter a strange runtime error. Here is a small example that is able to reproduce the error

Hi Could you please help me with the problem that the Cmake cannot find Boost_INCLUDE_DIR during the installation of the Dionysus. Thank you for your help. Best regards Vincent Sent from Mail for Wind

Hi all, I am working on a paper now that uses Dionysus 2. Does anyone know the proper citation to Dionysus 2? Is there a paper published that we can cite? Best, Pierre

Sorry to trouble, I am now using zigzag persistence to compute representative cycles of a rips complex but seems the generator is not what I want. For example see the data above, for 1-cycles I want a

Hi Dmitriy, Is there a quick way using Dionysus to find out the interval in which a given simplex exists as part of an alive component? For example, say the 1-simplex <a,b> joins the filtration at lev

Hi all, Is there a way to get the reduction matrix for the boundary matrix? To be precise, let D be the boundary matrix. With the column reduction, we obtain DV=R. I wonder if there is a function to o

You should search this forum for previous discussions of installation on Windows. The specific problem you are seeing is that you don't have C/C++ compilers installed, or at least CMake is not finding

hello.My pathon verion is ,my boost version is 1.7.0,i have installed mingGW8.10,and when i follow the process on this link https://groups.io/g/dionysus/topic/build_under_windows/32045298?p=,,,20,0,0,

hello. Now i have a problem about my project.It is urgent.And i want to ask you and look for your help. I have try the package of the dionysus, i mkdir cd cmake and make.And then i copy the folder in

Hi all, I am very new to topological data analysis and dionysus. To test my understanding, I am doing the following exercise: 1) Create a data cloud that is a perfect circle with diameter 1 2) Plot th

Hi, I've tried to install Dionysis (latest version) with pip on Ubuntu (18.04). I have multiple Python versions available, and I have first downloaded Boost, and built it specifying Python version. Al
