Reading DCD: UnicodeDecodeError: unexpected end of data

[girl_toon@…]

Hi

How to handle this error?

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc3 in position 0: unexpected end of data

File "C:\Program Files\ChimeraX\bin\lib\site-packages\chimerax\md_crds\dcd\MDToolsMarch97\md_DCD.py", line 175, in
dat = [c.decode('utf-8') for c in up('80c',f.read(cs('80c')))]

See log for complete Python traceback.

          Thanks

Hi,

The error seems to indicate that your DCD file is truncated. Does the file work in other applications, such as regular Chimera or VMD?

The DCD file was very big, so I cut few frames using catdcd, but it opened with VMD.

None of the DCD files I have access to exhibit this problem. Is there any chance you could use catDCD to produce a small DCD file and, assuming it still produces this error, send it and the associated structure file so that I can investigate further?
