erosion and dilation for EM (mask) maps ?
by Benjamin SCHWARZ 14 Mar '11

14 Mar '11

Hi list, I was wondering if anything would already exist to perform erosion and dilatation operations (i.e. remove / add a shell of n pixels on the border) on EM masks ? --Ben(S)

Re: [IMP-users] IMP-users Digest, Vol 10, Issue 2

Thank you for the reply Daniel. I want to have something similar to the rigid body mover, except when the RigidBody object is moved, objects which are related to it by a Cn symmetry operation are moved in such as was as to preserve the symmetry, just as SymmetrySampler samples when using domino. I have tried this by adding an overloaded RigidBodyMover constructor which takes in a Particles*, and by creating a new 'SymmerticalRigidBodyMover' class in the core model. However, after re-compiling, _IMP_core.so doesn't contain the new functions and crashes when I try to import IMP into python. I've also tried creating a new module containg my desired Mover class, but it doesn't even compile.

If not, how could I impliment it as a mover. It isn't evident how I could impliment this using MoverBase, nor what the list of attributes are for. I'm unclear on exactly what you would want as your move set? Picking a random choice from a discrete set? Chances are that you want to use the X,Y,Z coordinate keys as the float attributes list when using the MoverBase (you can get those from IMP::core::XYZ::get_coordinate_keys()). If you then store a list of coordinate values in your Mover, you can pick one of those for each particle to be moved and do IMP::core::XYZ(p).set_coordinates(new_coordinates) to change them. Does that help? > Also, when reconstructing em maps, such as in particles2density, I get this warning: > WARNING could not find parameters for radius:8.16743 > EM map is using default params > > What does this mean, are the default params ok? Keren will have to answer this.

Symmetry
by Iain Moal 12 Mar '11

Hi, I am new to IMP so please fogive naievity! Is it possible to use IMP::domino::SymmetrySampler as a Monte Carlo mover? If not, how could I impliment it as a mover. It isn't evident how I could impliment this using MoverBase, nor what the list of attributes are for. Also, when reconstructing em maps, such as in particles2density, I get this warning: WARNING could not find parameters for radius:8.16743 EM map is using default params What does this mean, are the default params ok?

is there a wrapper function that gets algebra::Vector3Ds and returns a atom::Hierarchy ? if not i will write one .... :)

how to transcode voxel index vidx to voxel dim index i, j, k ?
by Benjamin SCHWARZ 04 Feb '11

04 Feb '11

Hi list, I couldn't find the function that computes the "index coordinates" of a voxel from its voxel index (somehow, the opposite of xyz_ind2voxel() function.) do you know if there is any ? --Ben

restraint set
by Keren Lasker 24 Jan '11

thought its relevant for all: if i create a RestraintSet rs and a restraint r that is added to the model and to rs if then i add rs to the model is r added twice to the model? keren.

calculating chi squared
by Robert Brynmor Fenwick 24 Jan '11

24 Jan '11

Hi I have a script that calculates and fits saxs profiles and have observed that the fits are worse than previously calculated. I have a test case that now fits much worse than before. I guess that there is something wrong. Any help would be appreciated. I have attached the two output files and the saxs input files. If you look at the two output files to see that they give slightly different results. Another problem that I have is that I can not calculate the chi square value that is in the output file from the data. Is this the expected behavior? Bryn -- R.
