Make sure you write out at most one of each type. Character input is case insensitive except for file names. CCP4 supports maps of several types. There are no header lines All reflections have the same format and number of columns The indices H, K, and L are in columns 1, 2, and 3, respectively. Visualization with your favorite graphics program can tell you if data is randomly or systematically missing. Map 2 is defined by structure factors in columns with labels Fcalc and Pcalc.

If this is not the case then you can use the unix AWK command to fix it.

CRAN - Package SFtools

Map 2 is defined by structure factors in columns with labels Fcalc and Pcalc. The resulting map will cover exactly a full unit cell.

If you read in a second structure factor file or you prepared the header information with the SET ALL command or by reading a density map then SFTOOLS will compare the header information on the second file with what is in the data base.

Commands that prepare tables also allow the user some control over the table creation. Because the latter represent a unimodal phase distribution, only the A and B coefficients are generated. You will always get coefficients for all reflections that are already in the data base even if they are unselected.

MTZ If no columns are given, then the program will ask the user for each column whether or not to include it. When a second or more structure factor file is read, the program will add new columns to the data base to store the data from the new file.

A column may even be listed more than once!

Bins can be either as function of resolution or as function of another column. It will ignore character data amidst reflection data but you must edit out header lines try the unix TAIL command. It will report inconsistencies, but in all cases the information in the data base will be kept. The list of commands can always be obtained by just pressing the return key when the program asks for a command.

It is also essential to have correct column types for phases and anomalous differences, to distinguish: Also, all lines must have the same format as the first line s. However, to get a reasonable number of shells they have to be thinner than I would like.

The user will also have to update the cell parameters and or space group if needed. Phase information is stored in radians but they will appear in degrees to the user as long as the column type is set to "P". For CCP4 maps not all map types may be supported, but the standard electron density maps should work.

At the same time the program aftools many checks to protect you, as far as possible, from using the flexibility inappropriately. In the latter case the reflections are sorted by the other column before binning.

SFTOOLS (CCP4: Supported Program)

The codes follow the MTZ definition for column types. CCP4 supports maps of several types. The program input is analyzed by a parser that divides the input into words. The original default is 20 You can give only one keyword at a time, but if you give the CORREL keyword the program will automatically give you the r.

Use the Unix awk command to force all reflections to have the same format or to place the indices in the first three columns: Make sure you srtools out at most one of each type. The program CAD can be used to change the attributes of a dataset, and to change the assignment of columns to datasets, and this functionality is accessible through the Edit MTZ Datasets interface.

The file format will in most cases be determined from the file name extension, see below.

So the AND operator is the default. Most options will probably work fine with them but this has not been tested.

The results are also saved in a. If you leave out the arguments 3 things can happen: It also gives an R-value but this only makes sense if the columns are on the same scale. The correlation between two maps can be calculated when the structure factors of both maps are known amplitudes and phases. By default the CCP4 definition is used and it is recommended not to deviate from that.
