Spectra

Manuelito is a Java tool for decrypting posttranslational modification (PTM) patterns of proteins based on MALDI mass spectrometry spectra. It was built for analysing the 'histone code' but it can be applied to any other highly modified protein.

Queries the NIST ASD lines1.pl webform using wget and parses the returned output using sed and matlab intrinsics. Probably could be optimized, but works OK for the meantime.

This script acts to import files from Gatan's .DM3 file format, utilized for electron microscopy, into a MATLAB structure. The fields of the MATLAB structure can then be referenced with the dot-operator.For example, one can load and display a file with the appropriate scaled axes in nanometers...

Display image with non-linearly spaced axis.UIMAGE(X,Y,C) displays matrix C as an image, using the vectors X and Y to specify the X and Y coordinates. X and Y may be unevenly spaced vectors, but must be increasing. The size of C must be LENGTH(Y)*LENGTH(X). (Most probably you'll want to display...
