TSC produces a file eqdska. This file can be converted to a NetCDF file eqdsa.cdf using the tsc2cdf utility. The eqdsa.cdf can then read by J-Solver after setting IFUNC2=4 in inequ.
Note that some TSC versions dump 8-byte long integers into the eqdska file. Long integers are not portable. If you suspect this to be the case try using the tsclong2cdf utility on a platform that supports 8-byte long integers. This produces a eqdsa.cdf file that is fully portable.
