Additionally I've tried using a single class-average image from Relion as the Reference image for the alignment (I selected one good class-average in relion and imported the class_averages.mrcs file into eman using the 'import particle' tool which created a job16-class_averages.hdf file which I tried to use with the e2a2d_align.py I got a whole screen of script the last of which said /home/loca/software/eman/2.2/lib/python2.7/lib-dynload/_json.soAborted

Again a m2d_01 directory was created containing the there files but still an error message that no particle alignment data found for iter= 1

Subject: [ccpem] e2motion.py problems

I've used e2motion.py in the past to get an animation of the movement range of my protein however the last couple of times trying it I cant seem to get it to work;

when using;
e2motion.py --path m2d_01 --iter 1 --threads=16

I get the message:

Warning: no particle alignment data found for iter= 1

I had previously used the:

e2a2d_align.py particles/particleMRC.hdf particles/RefImageMRC.hdf --align rotate_translate_tree --aligncmp ccc --cmp ccc --threads=16

I thought this had worked as it created the directory 'm2d_01' which contained three files:

0_a2d_parms.json
particle_parms_01.json
refimg_01.hdf

Any idea where this might be going wrong?

The particle.hdf was an mrc stack containing 1663 particle images. The Reference Image was also an mrc stack from a single Relion Class Average containing 191 images. Should the Reference image be just a single class-average image and if so do you know how I would get this from relion?

Thanks for your help,

Sonya
