MuhRec supports input projection data in the formats: TIFF, FITS, and NeXus. Normally the filenames of the projections are sequentially ordered and each file has a base name and an index number. To enter the file name in the projection entry field you should use the format base_####.ext. The number of # tells MuhRec how many zeros to use in the formatting. The #'s can be placed anywhere in the name string. The extension indicates which file format to use.

Below the file name field the file interval can be entered with first and last file index. These indices will both both included. In addition there is also an entry to set the increment. This increment can be used to decrease the number of projection in test reconstructions. This saves time, but do not forget to repeat the reconstruction with all projections before you start the final reconstruction.

An alternative way to enter the projection data with a text file. The advantage of this approach is that you can use any filename and for each projection and you can specify the acquisition angle for each projection. The format of the file is

angle0 \<tab\> fileA.ext
angle1 \<tab\> fileB.ext
.
.
.
angleN \<tab\> fileXYZ.ext

Then you use a text file to specify the projection data. Valid extensions on the list file are '.txt','.lst', and '.csv'. You can use the file index numbers to select intervals in the file list. The first line in the file has index 1. Stepping does not work.

Once you have entered all projection information you can press the 'Preview'-button and the first projection will appear in the viewer. The displayed projection is the raw projection.
