's/\r//' = replace string between first slashes with string between second slashes = replace \r with nothing = remove \r (carriage return) > Which editor can show the carriage return symbols, such as '^M'? e.g. vim.

However, if I used the code to create a new translated file, I could load it without any problem. After diffing the files, it turned out that in the original files there are "^M" (carriage return) symbols at the end of lines. How/where/on which OS have you produced the translated files? using terminal command sed -i 's/\r//' initial_spheres_translate_x.txt fixes the problem cheers Jan -- You received this question notification because your team yade-users is an answer contact for Yade. ___ Mailing list: https://launchpad.net/~yade-users Post to : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp

[Yade-users] [Question #688690]: pack.SpherePack.save() function saved particles data format
New question #688690 on Yade: https://answers.launchpad.net/yade/+question/688690 Hi. I have a file of spherical particles saved by function of pack.SpherePack().save(). It has the format as follows, 0.000919246 0.000859971 0.000602774 1.20067e-05 -1 0.000959836 0.00055149 0.000975021 2.11065e-05 -1 . I want to translate all the particles in x direction and conduct it by the following python code, === === import numpy as np data = np.loadtxt('initial_spheres.txt', delimiter=' ', skiprows=0) with open('initial_spheres_translate_x.txt','w') as fd: for i in range(len(data)): fd.write('%.9f %.9f %.9f %.5e %d\n' % (data[i,0]+0.5e-3, data[i,1], data[i,2], data[i,3], -1)) === === and i got the data as this, 0.001919246 0.000859971 0.000602774 1.20067e-05 -1 0.001959836 0.000551490 0.000975021 2.11065e-05 -1 The format seems the same, however, there is an format error when reading the file by pack.SpherePack().load() function. By the way, i have tried the delimiter as space and tab and both don't work.
