[Chimera-users] how to color an model by an attribute in chimerax

[sunyeping]

Dear Elaine,

Thank you for your reply. The attribute file entropy.txt is available at 

https://drive.google.com/file/d/1oG0O4zKqw-uD5SeLTrAu16c3Jh8m3LG5/view?usp=sharing

Could you please help check whether the format is correct"?

I cannot figure out how to open this attribure file in chimera. When I input "open entropy.txt format defattr" in chimerax, I get the following error message:

Invalid "format" argument: Should be one of 'aln', 'amira', 'apbs', 'bild', 'brix', 'ccd', 'ccp4', 'cellpack', 'cmap', 'cmd', 'collada', 'compiled python', 'cube', 'dcd', 'delphi', 'dicom', 'dock', 'dsn6', 'dv', 'emanhdf', 'fasta', 'fsc', 'gltf', 'gopenmol', 'hdf', 'hssp', 'html', 'ihm', 'images', 'imagic', 'imod', 'imodmap', 'ims', 'macmolplt', 'markers', 'mmcif', 'mmtf', 'mol2', 'mrc', 'msf', 'netcdf', 'obj', 'pdb', 'pdbqt', 'pfam', 'pif', 'pir', 'positions', 'priism', 'profec', 'pseudobonds', 'python', 'rsf', 'sdf', 'segger', 'session', 'sff', 'situs', 'smiles', 'spider', 'stl', 'stockholm', 'storm', 'swc', 'tom_em', 'trr', 'uhbd', 'uniprot', 'vtk', 'web fetch', 'xplor', or 'xtc'

Could you tell me what is the correct way to open the file?

Thank you,
Best,
Yeping

Subject:[Chimera-users] how to color an model by an attribute in chimerax

Dear all,

I wish to color an model  by an attribute in chimerax. The attribute is the entropy which is calculted by an external software. I wrote the entropy values of each residue in a text file (attr.txt) like the following:

attribute: entropy
match mode: 1-to-1
recipient: residues
 :1 0.0
 :2 0.0014948
 :3 0.0090952
 :4 0.0004805
 :5 0.1102497
 :6 0.0095258
 :7 0.0008226
 :8 0.0042205
 :9 0.0037255
 :10 0.0006678
 :11 0.0027988
 :12 0.0193925
 :13 0.0153925
 :14 0.0052115
 :15 0.0020136
..........

However, when I input the command "color byattr attr.txt", I get the following error information:
"No known/Registered attribute attr.txt"

Could anyone tell me what is the correct way to do this?

With many thanks.

Best regards
