Troubleshooting and support

If you are experiencing problems with CMol, please check the Known Issues section of the website (www.cmol.org.uk) first to see if your error is listed. It may give information if it is possible to work round the issue, and some indication of when the update is likely to be fixed.

If your problem is not listed, please send a detailed description of the issue to support@cmol.org.uk. If we can reproduce the problem we will list it on the Known Issues page, and work to solve the issue for the next update to CMol. Please include relevant screenshots, PDB files or crash logs. To obtain a crash log, sync your iPhone or iPad to iTunes, and obtain the data from the following locations:

Mac: ~/Library/Logs/CrashReporter/MobileDevice/[DEVICENAME]

Windows: C:\Documents and Settings\[USERNAME]\Application Data\Apple computer\Logs\CrashReporter\[DEVICENAME]

Kindly attach the relevant log to the email that you send if you experienced a crash.

Rendering large molecules

CMol has been tested on the iPhone 4 and the iPad for molecules up to 18,000 atoms. However, loading larger molecules for these devices can require more memory than is available. In these cases, options are available to skip rendering of certain representations to free memory, but very large molecules may lead to instabilities and crashes. No limit has been placed on the number of atoms CMol can render due to different device capabilities and states of memory.

It is recommended that you have as few background processes running as possible whilst rendering large molecules, have as few windows open in Safari and no music playing in the background.
