So I am trying to make a Numpy Array based on this set of numbers I have that is without a header and split based on space (my objective is to remove the arrays with ALL zeroes). this is the code I have:

with open('/Users/name/Desktop/PDB/test_d3psm_misc/d3ps.profile','r') as f:
    for line in f:
        r = line.split(" ")
        print(r)

my output:

['0.1\t0.0\t0.0\t0.0\t0.0\t0.0\t0.0\t0.0\t0.0\t0.0\t0.0\t0.0\t0.0\t0.0\t0.0\t0.36\t0.54\t0.0\t0.0\t0.0\t\n']

I dont understand why this is happening. If there is an easier why to parse a bunch of files with numbers in it finding those that are ALL zeroes that would be better :)

import pandas as pd

df = pd.read_csv("/Users/name/Desktop/PDB/test_d3psm_misc/d3ps.profile", sep="\t", header=None).astype(float)
df = df.loc[df.sum(axis=1)>0]

Then, if you want to convert in numpy array:

df = df.to_numpy()
  • Thank you! The .astype(Float), could you explain that part please? And also the (sum(axis=1)>0] portion – Francesca C Jan 27 '22 at 13:17
  • @fsc8907 `astype(float)` converts your data in float numbers; I think that in your case is not necessary, but I wanted to be sure. In the second line you sum the numbers in the same row (`axis=1` means that you want to sum along the columns axis, preserving the number of rows) and if this sum is > 0 (meaning there is at least one positive number) you take that row. Note that this algorithm may not work if there are some negative numbers in your data. – Salvatore Daniele Bianco Jan 27 '22 at 14:24
  • Thank you kindly! Makes perfect sense....but what if I want to select those that are equal to zero? Cause what I am doing is taking checkpoint files that look like the photo in my post here: [link](https://stackoverflow.com/questions/70895269/output-is-an-empty-file?noredirect=1#comment125332188_70895269) and filtering just those that have the zero in the profile portion, so that I can remove it from the dataset! – Francesca C Jan 28 '22 at 15:14
  • @FrancescaC sorry i didn't properly understand what is the output your are interested in. Do you need in output the indexes of the all-zeros columns? – Salvatore Daniele Bianco Jan 28 '22 at 15:58
