Use one of the 3D EM software packages such as EMAN or Spider (both read in CCP4 maps, and EMAN even maintains pixel size and other parameters) EMAN: http://blake.bcm.tmc.edu/eman/eman1/progs/project3d.html Spider: http://www.wadsworth.org/spider_doc/spider/docs/man/pj3q.html Best, Petr ----------------------------------------------------------- Petr Leiman Head of the Laboratory of Structural Biology and Biophysics Institut de physique des systèmes biologiques École Polytechnique Fédérale de Lausanne (EPFL) Cubotron/BSP-415 CH-1015 Lausanne Switzerland Phone: +41 21 69 30441 Mobile: +41 79 538 7647 Fax: +41 21 69 30422 > > Best regards, > > Dirk. > > -- > > ******************************************************* > Dirk Kostrewa > Gene Center, A 5.07 > Ludwig-Maximilians-University > Feodor-Lynen-Str. 25 > 81377 Munich > Germany > Phone: +49-89-2180-76845 > Fax: +49-89-2180-76999 > E-mail: [log in to unmask] > WWW: www.genzentrum.lmu.de > *******************************************************
