The following tasks belong to the category MANIPULATION:

- AXSWAP
- Swap first and second axis of 2-dim (sub) set and/or change the sign of the grid separation. (axswap.c)
- BLOT
- Conditional transfer of maps using blotch region. (blot.c)
- CBLANK
- Converts datavalues to BLANK and vice versa. CBLANK also checks whether the data are legal (i.e. it checks for NaN's etc. and replaces them by BLANKS). (cblank.shl)
- CLEAN
- This program cleans maps or lines. (clean.c)
- CLIP
- Blank values of input if they are outside range. (clip.c)
- COMBIN
- Combine sets to create new sets using mathematical expressions. (combin.shl)
- CONDIT
- Transfer values if test value within certain range. (condit.c)
- COPY
- Program to copy set and subsets. It can also increase or decrease the frame size of the subsets. BLANKs will be written in the output set outside the original subset frame. (copy.shl)
- DECIM
- Decrease size of a set in any direction with an integer factor (decim.c)
- DIMINISH
- Program to copy set and subset. It will only copy the subset axes to the output set, so you can diminish the dimensionality of a set. (copy.shl)
- EDITSET
- Program to edit data in a set. (editset.c)
- ENHANCE
- Enhance image (Local enhancement method) (enhance.c)
- FFT
- This program does a two-dimensional Fast Fourier Transform on a (pair of) map(s). Maximum map size is 2048 x 2048. (fft.c)
- INSERT
- Program to insert (multiple) (parts of) a set into another existing set. (insert.shl)
- MIRROR
- Mirrors a two-dimensional image in x, y or both. It can also rotate the image over +90 or -90 degrees. (mirror.c)
- MNMX
- This program finds the minimum and maximum value in a subset or part of a subset. It also counts the number of blanks. (mnmx.shl)
- MOMENTS
- Program to calculate moments and other properties of a profile (moments.c)
- PATCH
- Find data values at positions of blanks interpolating the data in a small volume around the blanks. (PATCH)
- PBCORR
- Corrects maps for primary beam correction (pbcorr.shl)
- REGRID
- Create an output map with different grid along one axis. (regrid.c)
- REPROJ
- Reproject a spatial map into another map with a different coordinate system. (reproj.c)
- SCALE
- Program to scale the data in subsets by a factor and an offset. (scale.shl)
- SHUFFLE
- The programme shuffles profiles in a set so that they are aligned on positions taken from another set. (shuffle.c)
- SIGDET (SIGnal DETection)
- Separate signal from noise in image. (sigdet.c)
- SLICE
- Make a slice through a set (slice.c)
- SMOOTH
- Smooth sets with a gaussian beam (smooth.shl)
- .....
- Replace values by a box with other values e.g. for removing a bad perimeter of an velocity field. (snapper.c)
- TRANSFORM
- Transform a (sub)set using rotation, scaling, translation etc. (transform.c)
- VELSMO
- Program does a one dimensional smoothing of subsets. (velsmo.shl)
