Error when using gsd.hoomd.open

[Yuchen Xi]

Hi all

I trying to open a gsd file and extract particle position data. Below is the related script:

t = gsd.hoomd.open(name='1e7,gamma=1.gsd', mode='rb');

for i in range(len(t)):

    snap = t[i];

    np.savetxt('Conf' + str(i) + '.txt', snap.particles.position, fmt='%f', delimiter=',', newline='\n')  

I always get the error: OSError: [Errno 9] Bad file descriptor: '1e7,gamma=1.gsd'. I am pretty sure that the directory is right, and the gsd package is updated. Has anyone had the same issue before?

Thanks

Lawrence

Lawrence,

gsd.hoomd.open will open files from your current working directory when you give it a relative path. I would expect this error if the file "1e7,gamma=1.gsd" does not exist in the current working directory.
