I hope this makes sense. I have a Python script that reads an input (created from csv with commmas stripped out) file of geographic coordinates and I get this error:

forrtl: severe (24): end of file during read. unit 23 file /home/filename

This seems to relate that the code was expecting an EOF in the input file but this was perhaps absent. Would someone be able to tell how I check for this in the input file and what keystroke(s) are required for an EOF and exactly where this is placed. this is an extract of the script that creates the file:

f = open(file_ls, "w")
#first line contains 3 integers: the grid dimension, nx and ny, and the total number of snapshots nt
print("%d %d %d" % (np.shape(kxx)[1], np.shape(kxx)[0],     collapse_steps), file(f))
# then it follows by the X coordinates of gridded data (from lines 2 to nx+1), Y coordinates of gridded data (from lines nx+1 to nx+ny+1), and the times at which the snapshots are created (from lines nx+ny+2 to nx+ny+nt+1)
for ii in np.arange(np.shape(kxx)[1]):
        print("%.8f" % (kxx[0, ii]), file(f))
# for ii in arrange(shape(kyy)[0]):
for ii in range(np.shape(kyy)[0] - 1, -1, -1):
print("%.8f" % (kyy[ii, 0]), file(f))
for ii in np.arange(collapse_steps):
mytime = collapse_times[ii] + collapse_starttime
print("%.8f" % mytime, file(f))

# all the nt snapshots of seafloor variation are written into a single column one by one from t=t1 to t=tn; for each snapshot, deltah, the data should be written row by row from the left (i=1) to the right (i=nx) from the bottom (j=1) to the top (j=nx)
# deltaH > 0 corresponds to UPLIFT
# deltaH < 0 corresponds to SUBSIDE

deltaH = elev_t0 - elev_t1
###### time - start of collapse => initial bath => zero difference ??? bit stupid ??? check w/comcot sources
for ii in np.arange(np.shape(elev_t1)[0]):
for jj in np.arange(np.shape(elev_t1)[1]):
    print("%.8f" % 0.0, file(f))

for ii in np.arange(np.shape(elev_t1)[0]):
for jj in np.arange(np.shape(elev_t1)[1]):
    print("%.8f" % (deltaH[ii, jj]), file(f))

f.close()
