Before I write this reader, can I ask if it's possible you could use another format? Do you have all these files already made, so you are eager to use them exactly, or do you have a program that produces them? Because if it's a program that produces them, I suggest doing a little modification to

Xiang, I would suggest that whatever software you use to produce the ALC files is changed so that it produces MOL files. These have a well documented format specification and will be read by Jmol as well as RasMol. It seems that Alchemy format is rather old (there isn't even a mention of the p

Definitely no alchemy file format reader in Jmol. If someone can find me a specification, I'll create one. I'm a little concerned that the file format does not specify element -- assuming, for example, that "CAR" will be interpreted as carbon. I'd need to know what other aspects like that there mig

Does Jmol really support the Alchemy format? The Jmol main webpage does not mention it, the Jmol Wiki does (both are likely my fault). However, there are no example files in "Jmol-datafiles" folder at SVN. I tried the non-chemical file just reported by Xiang-Jun Lu and a molecule from Paul Bo

Hello Xiang I have no experience with Alchemy format, but yes it looks like a problem with the file reader. And I agree with Rolf, you have overlapping atoms, and "select all" reports 13 atoms. You should clean up your alc file. You have several ways to do this in Jmol (apart from having the
