I am trying to load .pdb files into avogadro but each time i do the programme crashes. here is a debug message from visual studios Unhandled exception at 0x77320DA2 (KernelBase.dll) in avogadro.exe: 0xC00000FD: Stack overflow (parameters: 0x00000001, 0x0EEA2FFC). occurred Does anyone know a solution to this? ---

It would really help to know: - What version of Avogadro you’ve downloaded? - What version of Windows you’re using It would also help to have an example of the PDB file. Are you opening a file from disk or from the Import -\> Fetch from PDB command? ---

I am using Avogadro version 1.2.0 with windows 10 professional version 1709 I am opening the pdb file from the disk, it opens fine in UCSF Chimera but not avogadro. ---

Is there an easy way for me to send you the pdb file I am looking at? Thanks for your help! ---

The easiest way is to put it on Dropbox or something similar and post the link. ---

[https://www.dropbox.com/s/i9a0uyekdrav0f9/3helixsquare\_multimodel-outfile.pdb?dl=0](https://www.dropbox.com/s/i9a0uyekdrav0f9/3helixsquare_multimodel-outfile.pdb?dl=0) This is a DNA structure, which displays nicely in UCSF chimera but not in Avogadro - it is a 3 helix bundle with strands running between helices – There should be one continuous strand running through the entire structure, supported by a number of shorter ones.
