Miguel Thank you for forwarding your solution. I have included it below so it can be sent to all board users. It will also go into the FAQ. Nigel Nigel, I think I found the answer. I put your file as a replacement of the original one, but got the same result. However, something told me that this could be a locale problem. My locale is Spanish and this causes some problems to programs such as ARP/wARP and Coot. The reason is that we use commas ',' to separate decimals from the integer part and dots '.' to separate powers multiple of 3; that is, the contrary of the English way. So I did: export LC_ALL=C phenix & And now it works (I have moved already to the third out of four screens in the demo) So, I would add the LC_ALL directive in my setup for phenix. Perhaps a FAQ with this would be a good idea for people in Spain, France and Germany ;-) I will let you know if there are any other issues. Thank you very much for your help!
