Do you think that a singe page for all the cartoon_helix types would be better than separate pages? e.g. putting the fance, normal, and cylindrical all on one page --Adam Shea

Yes I think it would be best to have all the cartoon_helix links of the settings page point to the same page. Do you know how to do that ? I think it would be less hairy/redundant than a 'related settings' section in multiple pages. --Philippe Garteiser

-Hi everyone !
+Do you think that a singe page for all the cartoon_helix types would be better than separate pages? e.g. putting the fance, normal, and cylindrical all on one page --Adam Shea
-I have created a script because I was tired of browsing the pdb for endless searches of structures relevant to my field. This scripts takes as input a text file in which you copied your favourite keywords, and the number of days you want to search back (by default, it will look at the structures added the last 50 days). It generates a report text file that contains the pdb id and name of the relevant structures that have been recently added. All you need to do is add 'run pdbsurvey.py' to your startup file, and create a text file called 'keywords.txt' with your keywords separated by an end-of-line character. Then you're ready to go. Just hit 'pdbsurvey' from within your PyMol instance, and the program returns the report file. The pdb ftp server is updated every tuesday.
+Yes I think it would be best to have all the cartoon_helix links of the settings page point to the same page. Do you know how to do that ? I think it would be less hairy/redundant than a 'related settings' section in multiple pages. --Philippe Garteiser
